Quality Control

Our Phenmedipham D3 is manufactured under strict quality control protocols to ensure the high chemical and isotopic purity required for analytical standards. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR, HPLC, and LC-MS, to confirm identity, deuterium incorporation, and purity. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. This material is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and purity. Allow the sealed vial to equilibrate to room temperature before opening to prevent moisture condensation.
