Quality Control

Our 3-Methanesulfonamido-4-Methylbenzoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and heavy metals, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing all specifications and test results.

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 after opening to prevent degradation from atmospheric moisture.
