Quality Control

Our 1-Hydroxy-3-Phospholene 1-Oxide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing including HPLC, NMR, and FTIR to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, providing full traceability and compliance with your internal quality standards.

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). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed under an inert atmosphere such as nitrogen to prevent degradation. Keep away from strong oxidizing agents.
