Description

Cefprozil is a broad-spectrum, second-generation cephalosporin antibiotic effective against a wide range of gram-positive and gram-negative bacteria. Its primary commercial value lies in its use as a key active pharmaceutical ingredient (API) for the formulation of oral antibiotic medications. This compound is essential for pharmaceutical manufacturers and research institutions developing treatments for respiratory tract, skin, and soft tissue infections.

Application

• Pharmaceutical API: Primary use as the active ingredient in oral antibiotic tablets, capsules, and suspensions.
• Human Medicine: Formulation of medications for treating bacterial infections such as otitis media, pharyngitis, tonsillitis, and bronchitis.
• Veterinary Medicine: Potential application in veterinary pharmaceuticals for treating bacterial infections in animals.
• Research & Development: Used in biochemical research for studying bacterial resistance mechanisms and developing new antibiotic derivatives.
• Reference Standard: Serves as a high-purity chemical reference standard for quality control and analytical testing in laboratories.

Quality Control

Our Cefprozil is manufactured under strict quality management systems, targeting compliance with major pharmacopoeial standards such as USP and EP. Every batch undergoes comprehensive analytical testing including identification, assay, impurity profiling, and residual solvent analysis to ensure it meets the stringent requirements for pharmaceutical actives. A Certificate of Analysis (COA) detailing all test results is provided with each shipment.

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 to prevent moisture absorption, which can affect stability and potency. Keep away from incompatible materials.
