Quality Control

Our 4-Amino-2-Methoxyphenol Hydrochloride is produced under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC for assay and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and related substances is provided with every shipment to support your quality assurance protocols.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and handling properties.
