Quality Control

Our Atorvastatin Ellyl Ester is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for pharmaceutical synthesis. We adhere to ICH guidelines for impurities and provide comprehensive Certificates of Analysis (COA) with each shipment, detailing identity, purity, and impurity profiles as confirmed by HPLC, NMR, and other analytical techniques.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed in a dry environment and away from direct light exposure to maintain stability and purity.
