Quality Control

Our 3-Carboxyethyl-2-Methylbenzoxazolium Bromide is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and loss on drying to verify moisture content. We provide full traceability and Certificates of Analysis (COA) are available upon request to ensure it meets your specific research or production requirements.

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 prevent degradation from atmospheric moisture.
