Quality Control

Our production of 2-(4-(4-N,n-Dimethylanilinyl)-1,3-Butadienyl)-3-Propyl-Benzothiazolium adheres to stringent quality protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR for structural confirmation, and spectrophotometry for optical property verification. Certificates of Analysis (COA) detailing batch-specific results are available upon request to ensure transparency and meet your R&D or production specifications.

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 hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. For long-term storage, consider using desiccants or an inert atmosphere.
