Quality Control

Our H-Met-Lys-Oh is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral analysis for enantiomeric integrity, and identity confirmation via mass spectrometry (MS) and infrared (IR) spectroscopy. Certificates of Analysis (COA) detailing all specifications are provided to ensure traceability and compliance with your research or cGMP requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C (refrigerated) or as specified on the label or COA. This material is hygroscopic (moisture-sensitive) and must be kept under anhydrous conditions. Allow the sealed container to reach room temperature before opening to prevent condensation.
