Quality Control

Our production of p-Chlorothiobenzoic Acid S-2,3-Epithiopropyl Ester adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure consistency and meet exacting customer specifications. 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 area at a controlled room temperature (typically 15-25°C). Keep away from strong oxidizing agents, strong bases, and sources of heat or ignition. Due to the reactive epoxide moiety, handle and store under an inert atmosphere (e.g., nitrogen) for long-term stability.
