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.
