Quality Control

Our 3,7-Bis(Diethylamino)-1-Methoxyphenoxazin-5-Ium Chloride is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, spectrophotometry for color value, and identity confirmation via IR and NMR. We provide a Certificate of Analysis (COA) with every shipment, detailing all specifications and test results to ensure traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a desiccated environment and handled under low-light conditions to maintain stability and prevent degradation.
