Quality Control

Our 1-Butyl-2-(2-[3-[2-(1-Butyl-3,3-Dimethyl-1,3-Dihydro-Indol-2-Ylidene)-Ethylidene]-2-Chloro-Cyclohex-1-Enyl]-Vinyl)-3,3-Dimethyl-3H-Indolium Hexafluorophosphate is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer or research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and handled under low-light conditions to prevent degradation. For long-term storage, consider storing under an inert atmosphere such as argon or nitrogen.
