Quality Control

Our 2-[4-[(Acetyl)Phenylamino]-1,3-Butadienyl]-3-(3-Sulfonatopropyl)Benzoxazolium is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing batch-specific results are available upon request to support your quality assurance and regulatory needs.

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