Quality Control

Our production of 1,2-Benzenediol, 4-Bromo-5-Methyl- (9Ci) adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets exacting customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment, guaranteeing traceability and compliance with relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its properties of being light-sensitive and easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation to maintain optimal purity and stability.
