Quality Control

Our 2-Aminoethanethiolsulfuric Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide detailed Certificates of Analysis (COA) that include results from HPLC, titration, and spectroscopic methods. While produced to high-purity standards suitable for research and industrial synthesis, specifications can be aligned with specific project requirements, including potential compliance with ICH guidelines for pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, store under dry, inert conditions such as nitrogen or argon atmosphere to prevent oxidation and moisture uptake. Recommended storage temperature is between 2°C and 8°C for long-term stability. The storage area should be cool, dry, and well-ventilated, away from incompatible materials.
