Quality Control

Every batch of 20:4 Ps CAS NO 474967-17-4 is manufactured under strict quality management systems. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing batch-specific results for all critical parameters to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to prevent oxidation and hydrolysis. The material is hygroscopic (moisture-sensitive) and light-sensitive; allow the sealed container to reach room temperature before opening to minimize moisture condensation.
