| Purity | Research Grade (≥95%, ≥97%, ≥98%, or ≥99% by HPLC/1H NMR); Anhydrous Grade (packaged under inert atm |
| Molecular Formula | C₁₈H₃₈N⁺ I⁻ (or C₁₈H₃₉NI) |
| Molecular Weight | 395.4 |
| Appearance | White to off-white or light-yellow waxy solid or crystalline powder |
| Packaging | 1g/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 Indicators | Appearance — 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 Notes | Stored 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. |

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.
