Quality Control

Our 3-Hydroxy-2-Methylpropanoic Acid is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure it meets the highest standards of purity and identity. Certificates of Analysis (COA) are provided with each shipment, detailing all relevant specifications. We adhere to cGMP principles where applicable to guarantee supply reliability and traceability for our global B2B clients.

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 each use to prevent absorption of atmospheric moisture, which can affect product quality and stability.
