Quality Control

Our 3-Chloro-4-Methylbenzenesulfinic Acid Sodium Salt is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of our global B2B clients. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent oxidation and moisture absorption.
