Packaging1g/5g/10g/25g per glass vial or aluminum foil bag (for research); 100g/500g/1kg per HDPE bottle or sealed aluminum foil bag (for bulk synthesis); custom packaging under inert atmosphere (argon or nitrogen) for high-purity grades
Testing IndicatorsAppearance — Visual inspection; Identification — ¹H NMR (proton NMR in CDCl₃ or DMSO-d₆) or ESI-MS; Purity — HPLC (reverse phase) or elemental analysis (C, H, N, I); Iodide content — Ion chromatography or silver nitrate titration; Water content — Karl Fischer titration (coulometric); Halide purity (Br⁻, Cl⁻ content) — Ion chromatography; Melting point — Capillary melting point apparatus; TGA — Thermal stability and decomposition profile; Residual solvents — GC-MS; NMR for olefinic integrity (oxidation degree) — Integration of vinyl proton signals (~5.3–5.4 ppm).
Storage NotesStored in a tightly sealed, light-resistant container under inert gas (argon or nitrogen) in a cool, dry place (2–8°C for long-term storage). Protect from moisture, air, and heat. Avoid contact with strong oxidizing agents and strong acids. Hygroscopic — repeated opening under ambient conditions should be avoided.
Lead Time10 days
Used primarily as an organic ammonium ligand in the synthesis of layered halide perovskites for solar cells, LEDs (PeLEDs), and photodetectors. Functions as a surface passivation agent and spacer cation in 2D (Ruddlesden-Popper) and quasi-2D perovskite structures. Also utilized in colloidal synthesis of anisotropic metal halide nanocrystals and as a phase transfer catalyst in organic reactions.
