Quality Control

Every batch of 5-Chloro-2-(2-Ethoxybut-1-Enyl)-3-(3-Sulphonatopropyl)Benzoxazolium is subjected to rigorous analytical testing to ensure it meets stringent purity and performance criteria. Our quality assurance protocols are designed to support GMP and ISO 9001 aligned processes, providing traceability and reliability for your critical synthesis workflows. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment.

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 under anhydrous conditions to prevent degradation. Keep away from incompatible materials.
