Quality Control

Our 2-[2-[4-[(2-Chloroethyl)Ethylamino]-o-Tolyl]Vinyl]-1,3,3-Trimethyl-3H-Indolium Hydrogen Sulphate is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. Keep away from incompatible materials.
