Quality Control

Every batch of 1,3-Benzenediol, 2-Fluoro-4-Nitroso- is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure product identity, purity, and consistency for your critical R&D and scale-up processes. A Certificate of Analysis (COA) detailing specifications such as assay (HPLC), identity (IR, NMR), and impurity profiles is supplied with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flame.
