Description

N-OCTYLAMMONIUM BROMIDE C₈H₂₀BRN 99% OABR CAS 14846-47-0

RESEARCH GRADE MATERIAL

Product Overview
n-Octylammonium Bromide (C₈H₂₀BrN, OABr, CAS 14846-47-0) is a long-alkyl-chain organic bromide salt with C₈H₂₀BrN 99% purity OABr, supplied as a white powder with a molecular weight of 210.16 g/mol. This compound functions as a 2D layered perovskite spacer precursor, where the long octyl chain creates a steric barrier effect that passivates grain boundary defects in perovskite thin films while simultaneously blocking moisture ingress. The hydrophobic alkyl chain significantly enhances the environmental stability of perovskite optoelectronic devices by forming a protective organic layer between inorganic perovskite sheets. As the bromide analog of OAI, this precursor enables halide composition tuning in 2D perovskite systems. The material is widely utilized in university and research institute laboratories for two-dimensional perovskite solar cell, photodetector, and light-emitting device experimental research. Compatible with spin-coating and solution blending thin-film preparation techniques, this high-purity precursor requires strict light-sensitive hygroscopic dry storage to maintain material integrity.

Key Features & Advantages
  • Long Alkyl Chain Steric Barrier for Moisture Resistance: The eight-carbon octyl chain provides a hydrophobic steric barrier that effectively blocks moisture ingress into the perovskite lattice, significantly enhancing environmental stability compared to short-chain or aromatic ammonium counterparts.
  • Effective 2D Layered Perovskite Spacer Cation: OABr serves as the organic spacer layer in Ruddlesden-Popper phase two-dimensional perovskites, where the long alkylammonium cation templates the formation of quantum-well structures with enhanced exciton binding energy and tunable optoelectronic properties.
  • Bromide Analog for Halide Composition Tuning: As the bromide counterpart to OAI, this precursor enables independent control of both the organic spacer cation and halide composition in 2D perovskite systems, providing an additional degree of freedom for bandgap and stability engineering.
  • Ultra-High Purity Exceeding 99%: Refined to >99% purity with low batch impurity content, the precursor minimizes extrinsic defects in 2D perovskite thin films and supports reproducible device performance across experimental batches.

APPLICATION SCOPE: Organic spacer cation for 2D Ruddlesden-Popper phase layered perovskite synthesis. Grain boundary passivation agent for mixed 2D/3D perovskite thin films in high-stability solar cells. Bromide source for halide composition engineering in 2D perovskite systems. Moisture barrier precursor for environmentally stable perovskite optoelectronic devices. Compatible with spin-coating and solution blending deposition protocols. Supports two-dimensional perovskite solar cell, photodetector, and light-emitting device research in university and research institute laboratories where enhanced environmental stability is a primary experimental objective.
PACKAGING: This listing is for the 10 g specification. Other packaging weights are available upon custom request. Each package is sealed under inert atmosphere within light-protective packaging to prevent photodegradation and moisture ingress. The hygroscopic nature of n-octylammonium bromide necessitates immediate transfer to a desiccated, light-protected storage environment upon receipt. For bulk quantities or custom packaging specifications, please contact us via email.
IMPORTANT NOTICE: n-Octylammonium bromide is hygroscopic and light-sensitive. Tighten the container cap immediately after each use to prevent moisture ingress from ambient air. Wear protective gloves throughout all experimental procedures to avoid direct skin contact. Store in a light-protected, moisture-free environment; do not store together with strong oxidizing agents or acidic reagents. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. When preparing precursor solutions, handle the white powder within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm). For detailed safety and handling information, consult the Safety Data Sheet prior to use.

This compound is hygroscopic and light-sensitive, requiring storage in a dry, light-protected environment. It must be handled within an inert-atmosphere glovebox to prevent moisture-induced degradation and deliquescence.

  • Moisture Sensitivity: Exposure to atmospheric moisture causes deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry.
  • Light Sensitivity: Light exposure accelerates photodegradation, requiring storage in light-protective packaging and environments.
  • Glovebox Requirement: When preparing precursor solutions, handle the powder within an inert-atmosphere glovebox with H2O < 1 ppm and O2 < 1 ppm.
  • Incompatible Reagents: Do not store together with strong oxidizing agents or acidic reagents to avoid hazardous reactions.

Follow these steps to maintain material integrity by preventing moisture and light exposure. The steps cover initial storage, daily handling, and solution preparation protocols.

Required Equipment: Inert-atmosphere glovebox, Desiccator, Protective gloves

  1. Immediate Storage
    Transfer the material to a desiccated, light-protected storage environment immediately upon receipt.
  2. Cap Securing
    Tighten the container cap immediately after each use to prevent moisture ingress from ambient air.
  3. Long-Term Storage
    Store in a light-protected, moisture-free environment away from strong oxidizing agents and acidic reagents.
  4. Glovebox Handling
    Handle the white powder within an inert-atmosphere glovebox when preparing precursor solutions.
  5. Personal Protection
    Wear protective gloves throughout all experimental procedures to avoid direct skin contact.

How does the long alkyl chain of n-octylammonium bromide trade off moisture stability against charge transport in 2D perovskite devices?

The eight-carbon octyl chain provides a hydrophobic steric barrier that blocks moisture ingress more effectively than short-chain or aromatic spacers, enhancing environmental stability. However, as stated in the product description, this long alkylammonium cation templates quantum-well structures with enhanced exciton binding energy, which can reduce charge extraction efficiency compared to narrower quantum wells, representing a trade-off between stability and charge transport.

What inert-atmosphere conditions are required when handling n-octylammonium bromide for perovskite thin-film preparation?

The white powder must be handled exclusively within an inert-atmosphere glovebox with H₂O below 1 ppm and O₂ below 1 ppm to prevent moisture-induced deliquescence and hydrolysis that would irreversibly degrade precursor stoichiometry. This requirement is explicitly stated in the product's storage and handling instructions for solution-based deposition protocols.

What immediate post-receipt steps are critical to preserve n-octylammonium bromide integrity?

Upon receipt, the sealed package must be transferred immediately to a desiccated, light-protected storage environment. The container cap should be tightened immediately after each use, and storage must be at room temperature, away from strong oxidizing agents and acidic reagents. Failure to prevent atmospheric moisture exposure causes irreversible deliquescence and loss of stoichiometry.

n-Octylammonium Bromide (OABr, 99% purity) is a long-alkyl-chain organic bromide salt designed as a 2D perovskite spacer cation, offering moisture resistance via hydrophobic steric barrier and enabling halide composition tuning, but requires strict inert-atmosphere glovebox handling and light-protected dry storage to prevent degradation.
