Quality Control

Our (S)-2-Aminopropylsulfonic Acid is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including chiral purity analysis by HPLC, to ensure high enantiomeric excess (ee) and chemical purity. Certificates of Analysis (COA) detailing identity, assay, impurity profile, and chiral purity are provided and available upon request, supporting compliance with rigorous R&D and cGMP guidelines where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Recommended long-term storage temperature is 2-8°C.
