Quality Control

Our 1,3,3-Trimethyl-2-[3-(1,3,3-Trimethyl-2-Indolinylidene)Propenyl]-3H-Indolium Perchlorate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for advanced optical applications. Certificates of Analysis (COA) detailing purity, absorbance maxima, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize headspace in opened containers to prevent degradation.
