Quality Control

Our 5-Phenyl-3-Ethyl-2-(2-Methyl-3-(5-Phenyl-3-Ethyl-2,3-Dihydro-Benzoxazol-2-Ylidene)-1-Propenyl)-Benzoxazolium Ethylsulfate is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. All products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to verify identity and purity. Certificates of Analysis (COA) detailing all specifications 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 tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
