Quality Control

Our 4-Amino-3-Bromo-Phenol Hydrochloride is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for use as a synthesis intermediate. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting key parameters such as assay, impurity profile, and physical characteristics.

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