Quality Control

Our production of Pss-Trivinylsilyloxy-Heptacyclopentyl S& CAS NO 352538-79-5 adheres to a stringent quality management system. Each batch undergoes rigorous analytical testing, including NMR, FT-IR, and HPLC analysis, to ensure chemical identity, purity, and lot-to-lot consistency. Certificates of Analysis (COA) detailing all specifications are 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 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 or argon) after opening to prevent degradation.
