Quality Control

Our p-Dodecylbenzenesulfinic Acid Sodium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing specific results for assay, impurities, and physical parameters is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; containers must be kept tightly sealed after opening to minimize exposure to air and moisture. For long-term storage, consider using an inert atmosphere.
