Quality Control

Our Methyl 4-Amino-3-Mercaptobenzoate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize exposure to air and moisture.
