Quality Control

Every batch of α-(2-Oxopropyl)Benzenemethanesulfonic Acid Sodium Salt is produced and tested under a strict quality management system. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive testing includes identity confirmation, purity assay, and control of key impurities. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and consistent quality for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and handling properties.
