Quality Control

Our Phosphorodichloridothioic Acid S-sec-Butyl Ester is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee it meets the stringent requirements for research and industrial synthesis.

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). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation. Keep away from strong acids, bases, and oxidizing agents.
