Quality Control

Our production of 5-Methoxy-1,3,3-Trimethyl-2-[2-(1-Methyl-2-Phenyl-1H-Indol-3-Yl)Vinyl]-3H-Indolium Methyl Sulphate adheres to stringent quality protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and spectrophotometry for color value assessment. We provide comprehensive Certificates of Analysis (COA) with every shipment to ensure traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
