Description

Penicillin CAS NO 1406-05-9 is a foundational β-lactam antibiotic belonging to the penicillin class, renowned for its potent bactericidal activity against a wide spectrum of Gram-positive bacteria. Its critical role in combating bacterial infections makes it an essential active pharmaceutical ingredient (API) for the global healthcare industry. This product is primarily required by pharmaceutical manufacturers for the formulation of injectable antibiotics, as well as by research institutions for microbiological studies and drug development.

Application

• Pharmaceutical API Manufacturing: Primary use as the active ingredient in the production of injectable penicillin formulations for clinical use.
• Veterinary Medicine: Formulation of antibiotics for the treatment of bacterial infections in livestock and companion animals.
• Microbiological Research: Used as a selective agent in culture media and for studying bacterial resistance mechanisms in laboratory settings.
• Reference Standard: Serves as a high-purity chemical standard for quality control and analytical method development in pharmacopeial testing.
• Biochemical Studies: Employed in research to investigate the mode of action of β-lactam antibiotics and bacterial cell wall synthesis.

Quality Control

Our Penicillin is produced and tested under strict quality management systems to ensure it meets the rigorous standards required for pharmaceutical applications. Each batch is analyzed for identity, potency, and purity, with specifications aligned to major pharmacopeias such as USP and EP. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

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 low-humidity environment to prevent moisture absorption and degradation.
