Quality Control

Every batch of 5-Acetyl-2-Methylbenzenesulfonic Acid is manufactured under a strict quality management system and undergoes comprehensive analytical testing. We ensure consistent purity and identity through methods including HPLC, NMR, and IR spectroscopy. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee compliance with your project requirements.

Storage

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