Quality Control

Our Pyridinium, 1-7-2-(p-Aminophenyl)Acetamido-2-Carboxy-8-Oxo-5-Thia-1-Azabicyclo4.2.0Oct-2-En-3-Ylmethyl-3-Carbamoyl-, Hydroxide, Inner Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for pharmaceutical intermediate use. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and purity. Long-term storage under inert atmosphere (e.g., nitrogen) is recommended for optimal preservation.
