Quality Control

Every batch of n-[1-(Diphenoxyphosphinyl)-2-Phenylethyl]- Phenylmethyl Ester is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the compound meets the precise requirements for research and process development. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment, supporting your quality assurance and regulatory documentation needs.

Storage

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