Description

Ampicillin CAS NO 1207726-28-0 is a broad-spectrum semi-synthetic β-lactam antibiotic belonging to the aminopenicillin class. It is a critical active pharmaceutical ingredient (API) valued for its bactericidal activity against a wide range of Gram-positive and Gram-negative organisms. This compound is essential for the formulation of injectable and oral antibiotic medications, serving the pharmaceutical manufacturing, veterinary medicine, and research sectors.

Application

• Pharmaceutical API: Primary use in the manufacture of injectable and oral antibiotic formulations for human use.
• Veterinary Medicine: Formulation of antibiotics for the treatment of bacterial infections in livestock and companion animals.
• Research & Development: Used as a standard or experimental compound in microbiological studies, pharmacology research, and antibiotic resistance investigations.
• Reference Standard: Serves as a high-purity chemical standard for quality control and analytical testing in pharmaceutical laboratories.
• Intermediate Synthesis: Acts as a key starting material or intermediate in the synthesis of more complex antibiotic derivatives.

Quality Control

Our Ampicillin is manufactured and tested under strict quality management systems. It is suitable for use under cGMP guidelines for pharmaceutical active ingredients. Each batch undergoes comprehensive analytical testing including identification, purity assay, and impurity profiling via HPLC. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect stability and potency.
