Quality Control

Every batch of 2-Hydroxy-6-Methylbenzenesulfonic Acid is produced and tested under a strict Quality Management System. We ensure compliance with relevant industry standards through rigorous analytical controls. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing purity, identity, and impurity profiles as verified by techniques including HPLC, NMR, and titration.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and oxidizing agents.
