Quality Control

Our production of Phenol, 4-Amino-2-Chloro-5-Mercapto- adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including HPLC, GC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed after each use to minimize exposure to moisture and air.
