Quality Control

Our 2-Mercaptoacetanilide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment. We can support development projects with custom purity grades and analytical method development upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its property of being easily oxidized, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain optimal purity and shelf life. Keep away from strong oxidizing agents.
