Quality Control

Our 4-Mercaptobutyryl Carnitine Chloride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR, and specific tests for related substances and residual solvents. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, ensuring compliance with research and cGMP-grade material standards as required.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed after each use to minimize exposure to moisture and air.
