Quality Control

Every batch of Cytidine,n-Benzoyl-2'-C-Methyl-,3',5'-Dibenzoate(9Ci) is produced and analyzed under a strict quality management system. We ensure compliance with relevant industry standards for advanced pharmaceutical intermediates. Certificates of Analysis (COA) are provided with each shipment, detailing purity, identity, and impurity profiles as determined by HPLC, NMR, and mass spectrometry. Our quality commitment supports your regulatory and research needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using a desiccant.
