Description

N-HEXYLAMMONIUM BROMIDE C₆H₁₆BRN 99% HEXABR CAS 7334-95-4

RESEARCH GRADE MATERIAL

Product Overview
n-Hexylammonium Bromide (C₆H₁₆BrN, HexABr, CAS 7334-95-4) is a long-alkyl-chain organic bromide salt with C₆H₁₆BrN 99% purity HexABr, supplied as a white powder with a molecular weight of 182.10 g/mol. This compound functions as an effective 2D layered perovskite spacer precursor, where the six-carbon hexyl chain provides an intermediate-length hydrophobic barrier that modulates interlayer spacing in layered perovskite structures. The hexylammonium cation simultaneously passivates grain boundary and surface defects while blocking moisture ingress through the hydrophobic alkyl chain, significantly enhancing the environmental stability of perovskite optoelectronic devices. Compared to shorter butylammonium analogs, the extended hexyl chain offers increased hydrophobicity and larger interlayer spacing; compared to longer octylammonium analogs, it provides improved precursor solubility. The material is widely utilized in university and research institute laboratories for two-dimensional perovskite solar cell, photodetector, and light-emitting diode experimental research. Freely soluble in polar organic solvents including DMF and DMSO, this high-purity precursor is compatible with spin-coating and solution blending preparation techniques. Strict light-sensitive hygroscopic glovebox storage is required to maintain material integrity.

Key Features & Advantages
  • Optimized Intermediate Chain Length for Balanced Properties: The six-carbon hexyl chain provides an optimal balance between butyl (C4) and octyl (C8) ammonium analogs—offering enhanced hydrophobicity over shorter chains while maintaining superior solubility and processability compared to longer-chain counterparts.
  • Enhanced Moisture Barrier via Hydrophobic Alkyl Chain: The hexylammonium cation forms a robust hydrophobic protective layer at perovskite film surfaces and grain boundaries, effectively blocking moisture ingress and significantly improving device environmental stability under ambient conditions.
  • Precise Interlayer Spacing Modulation: HexABr enables fine-tuning of the perovskite quantum-well interlayer distance through its defined six-carbon spacer length, providing an additional structural parameter for optimizing charge transport and exciton confinement in 2D perovskite systems.
  • 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 layered and quasi-2D Ruddlesden-Popper phase perovskite synthesis. Interlayer spacing modulator for tuning charge transport and exciton confinement in layered perovskite structures. Surface and grain boundary passivation agent with hydrophobic moisture barrier functionality. Precursor for dimensionality engineering in mixed 2D/3D perovskite systems. Compatible with spin-coating and precursor solution blending deposition protocols. Supports two-dimensional perovskite solar cell, photodetector, and light-emitting diode research in university and research institute laboratories.
PACKAGING: This listing is for the 5 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-hexylammonium bromide necessitates immediate transfer to a desiccated, light-protected storage environment—preferably a nitrogen-filled glovebox for long-term storage. For bulk quantities or custom packaging specifications, please contact us via email.
IMPORTANT NOTICE: n-Hexylammonium 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; avoid direct skin contact. Store in a light-protected, moisture-free environment; do not store together with strong oxidizing agents or acidic reagents. Prioritize powder weighing and solution preparation within a nitrogen-filled inert glovebox (H₂O < 1 ppm, O₂ < 1 ppm). For long-term storage, inert-atmosphere glovebox conditions are recommended. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. For detailed safety and handling information, consult the Safety Data Sheet prior to use.
