Quality Control

Our Sodium Hydrogen 3-Methyl-5-[(4-Sulphonatophenyl)Azo]Salicylate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and UV-Vis spectroscopy, to ensure it meets exacting standards for chemical intermediates. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
