Quality Control

Our Cetophenicol is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive quality documentation, including Certificates of Analysis (COA) that detail purity, identity, and impurity profiles. The product can be supplied to meet various pharmacopeial standards, including USP and EP, upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 degradation from atmospheric moisture.
