Quality Control

Every batch of Chlorothiophosphonic Acid S-sec-Butyl o-Ethyl Ester is produced and tested under strict quality management protocols. We ensure high purity and consistency through advanced analytical techniques including GC, HPLC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee it meets your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its properties as a strong acid/organic solvent and being easily oxidized, it is recommended to store under an inert atmosphere such as nitrogen. Keep container tightly sealed when not in use to minimize moisture uptake and oxidation. Recommended storage temperature: 2-8°C for long-term stability.
