Description

METHYLAMMONIUM BROMIDE CH₃NH₃BR 99% CAS 6876-37-5

RESEARCH GRADE MATERIAL

Product Overview
Methylammonium Bromide (CH₃NH₃Br, CAS 6876-37-5) is an organohalide salt with CH₃NH₃Br 99% purity, supplied as a white crystalline solid with a molecular weight of 111.97 g/mol. This compound serves as the bromide source for MAPbBr₃ and mixed-halide perovskite formulations in perovskite solar cell fabrication research. The material is hygroscopic and requires strict light-sensitive dry sealed storage—maintained under inert atmosphere, protected from light, and kept at room temperature—to preserve stoichiometric integrity prior to precursor solution preparation.

Key Features & Advantages
  • High Purity Exceeding 99%: The methylammonium bromide is refined to >99% purity, minimizing extrinsic ionic impurities in perovskite thin films for reproducible device performance.
  • Precise Stoichiometric Control for Mixed-Halide Perovskites: With a defined molecular weight of 111.97 g/mol, the precursor enables accurate stoichiometric tuning of bromide-iodide ratios in mixed-halide formulations.
  • Flexible Custom Packaging: This listing is for the 10 g specification. Other sizes and specifications can be customized—please contact us via email for tailored orders.
  • Room Temperature Storage: The material is stored at room temperature under light-protected, dry, sealed conditions, simplifying laboratory inventory management without requiring refrigeration.

APPLICATION SCOPE: Primary precursor for wide-bandgap perovskite synthesis. Essential bromide source for mixed-halide formulations enabling bandgap tuning. Utilized in two-step sequential deposition protocols where the precursor solution is spin-coated onto pre-deposited films for in-situ perovskite conversion. Functions as the organic cation component in two-dimensional perovskite phases when combined with longer-chain alkylammonium spacer cations.
PACKAGING: This listing is for the 10 g specification. Each package is sealed under inert atmosphere within light-protective packaging to prevent photodegradation and moisture ingress. The hygroscopic nature of methylammonium bromide necessitates immediate transfer to a desiccated, light-protected storage environment upon receipt.
IMPORTANT NOTICE: Methylammonium bromide is hygroscopic and light-sensitive. Store in a desiccator or nitrogen-filled glovebox protected from ambient light at room temperature. Exposure to atmospheric moisture will cause deliquescence and hydrolysis, irreversibly degrading precursor stoichiometry. When preparing precursor solutions, handle the white crystalline solid exclusively within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm). Dissolve in anhydrous solvent immediately prior to use. Avoid exposure to strong oxidizing agents. For detailed safety and handling information, consult the Safety Data Sheet prior to use.
