Quality Control

Our p-Nitrophenyl 3-Amino-4-Methoxybenzenesulphonate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity assessment and spectroscopic methods for structural confirmation, to ensure it meets the high standards required for research and industrial use. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent exposure to atmospheric moisture, which can affect product stability and performance.
