Quality Control

Our Butanoic Acid, Hydroxymethyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity, identity, and consistency. We provide comprehensive Certificates of Analysis (COA) detailing purity, assay, and impurity profiles upon request, supporting compliance with cGMP and other relevant industry standards for intermediate chemicals.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent degradation from atmospheric moisture. Keep away from strong acids and incompatible organic solvents.
