Quality Control

Every batch of Rac-1-Palmitoyl-2-Linolenoyl-3-Chloropropanediol-D5 is manufactured and analyzed under strict quality systems. We guarantee high chemical and isotopic purity, confirmed by advanced chromatographic and spectrometric techniques. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing assay, isotopic enrichment, and impurity profiles to ensure it meets the exacting standards required for analytical and research applications.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., argon or nitrogen) to minimize oxidation and hydrolysis. The product is hygroscopic (moisture-sensitive) and should be handled in a dry environment. Allow the sealed vial to equilibrate to room temperature before opening to prevent condensation.
