Quality Control

Our 2-Amino-4-(Ethylsulfonyl)Phenol is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and consistent batch-to-batch reliability. 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, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive nature and propensity for oxidation, it is recommended to store under an inert atmosphere for long-term preservation. Keep away from strong oxidizing agents.
