Quality Control

Our 1H-Benz[E]Indolium, 3-[(4-Carboxyphenyl)Methyl]-1,1,2-Trimethyl-, Bromide (1:1) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure consistent quality and batch-to-batch reproducibility. Comprehensive Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request.

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 after opening to minimize exposure to atmospheric humidity. For long-term storage, consider using desiccants.
