Quality Control

Every batch of 6-[2-(3,4-Dihydro-4,4-(Dimethyl-D6)-2H-1-Benzothiopyran-6-Yl)Ethynyl]-3-Pyridinecarboxylic Acid is manufactured under strict quality management systems. Our products undergo rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and isotopic enrichment meet the stringent requirements for research use. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to maintain stability and purity.
