Quality Control

Our Eseridine is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including HPLC chromatograms and spectroscopic profiles (IR, NMR). A detailed Certificate of Analysis (COA) is supplied with each batch, confirming identity, purity, and conformity to agreed specifications. Our quality commitment aligns with cGMP principles for pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption. Keep away from incompatible materials.
