Quality Control

Our 3-Dansylamidomethyl-7-Beta(Thienyl-2')-Acetamidoceph-3-Em-4-Oate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and stringent control of residual solvents and impurities. We provide a detailed Certificate of Analysis (COA) with every shipment to ensure traceability and compliance with your research or cGMP guidelines.

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 product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. Keep away from heat and incompatible materials.
