Quality Control

Our Propyl Dichlorodithiophosphate is manufactured under strict process controls to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including chromatography and spectroscopic methods, to confirm identity and meet stringent impurity profiles. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and specific test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Keep away from strong acids, bases, and oxidizing agents.
