Quality Control

Our Isopropyl Hydrogen Methylphosphonite is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and titration to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and other critical parameters is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Due to its sensitivity to oxidation, containers should be kept sealed and purged with inert gas after each use.
