Quality Control

Our 3-(Hydroxymethyl)-p-Phenylenediammonium Sulphate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee traceability and 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product stability and performance.
