Description

N-BUTYLAMMONIUM BROMIDE C₄H₁₂BRN 99% BABR CAS 15567-09-6

RESEARCH GRADE MATERIAL

Product Overview
n-Butylammonium Bromide (C₄H₁₂BrN, BABr, CAS 15567-09-6) is a short-alkyl-chain organic bromide salt with C₄H₁₂BrN 99% purity BABr, supplied as a white powder with a molecular weight of 154.05 g/mol. This compound functions as a 2D quasi-2D perovskite spacer precursor, where the butyl chain length provides an intermediate steric barrier that modulates interlayer spacing in layered perovskite structures. The four-carbon alkylammonium cation effectively passivates surface and grain boundary defects while enabling controlled dimensionality engineering between strictly 2D and 3D perovskite phases. The material is widely utilized in university and research institute laboratories for photovoltaic cell, photodetector, and light-emitting diode 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
  • Intermediate Chain Length for Controlled Dimensionality: The four-carbon butyl chain provides an intermediate steric barrier between short-chain and long-chain ammonium cations, enabling fine-tuning of interlayer spacing and controlled dimensionality engineering in 2D and quasi-2D perovskite systems.
  • Effective Surface and Grain Boundary Passivation: The butylammonium cation selectively passivates surface and grain boundary defect states in perovskite thin films, reducing non-radiative recombination pathways while maintaining sufficient charge transport between perovskite layers.
  • Enhanced Environmental Stability for Optoelectronic Devices: BABr incorporation into perovskite structures improves resistance to moisture-induced degradation through hydrophobic protection at grain boundaries and film surfaces, extending device operational lifetime under ambient conditions.
  • Ultra-High Purity Exceeding 99%: Refined to >99% purity with low batch impurity content, the precursor minimizes extrinsic defects in quasi-2D perovskite thin films and supports reproducible device performance across experimental batches.

APPLICATION SCOPE: Organic spacer cation for 2D and quasi-2D Ruddlesden-Popper phase perovskite synthesis. Interlayer spacing modulator for tuning optoelectronic properties in layered perovskite structures. Surface and grain boundary passivation agent for mixed-dimensional perovskite thin films. Precursor for dimensionality engineering between 2D and 3D perovskite phases. Compatible with spin-coating and solution blending deposition protocols. Supports photovoltaic cell, photodetector, and light-emitting diode research in university and research institute laboratories.
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-butylammonium 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-Butylammonium 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.
