Quality Control

Our Propanoicacid,2-Methyl-,3-Hydrox is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) documenting purity, chiral purity (if applicable), and impurity profiles are available for every shipment. We support compliance with cGMP, ISO, and relevant pharmacopeial guidelines as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality and stability.
