Quality Control

Our Dichloroneopentyl-Phosphine is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopic methods, to ensure high purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its light-sensitive nature and reactivity, the container should be kept under an inert atmosphere (e.g., nitrogen or argon) to maintain stability and prevent degradation. Keep away from heat, open flames, and incompatible materials such as strong oxidizers and bases.
