Quality Control

Our production of Benzenesulfonic Acid, 3-[(1S)-1-Aminoethyl]- adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure high chemical and enantiomeric purity suitable for demanding synthetic applications. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic 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.
