Quality Control

Our Ammonium 3-Hydroxy-5-Methylbenzenesulphonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation by IR spectroscopy, to ensure it meets precise specifications. Certificates of Analysis (COA) are provided and available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
