Description

Cefadroxil is a first-generation, broad-spectrum cephalosporin antibiotic. It is valued for its excellent oral bioavailability and bactericidal activity against a wide range of Gram-positive and some Gram-negative pathogens. This API is essential for the formulation of solid and liquid dosage forms in the pharmaceutical industry, primarily targeting bacterial infections. Our supply of Cefadroxil CAS NO 66592-87-8 ensures high purity and reliable quality for critical manufacturing processes.

Application

Cefadroxil is a versatile active pharmaceutical ingredient (API) with established uses in human and veterinary medicine. Its primary applications include:

• Pharmaceutical Formulations: Core component in the manufacture of oral capsules, tablets, and suspensions for human use.
• Veterinary Medicine: Used in medicated feeds and treatments for bacterial infections in livestock and companion animals.
• Generic Drug Production: Serves as the key ingredient for generic antibiotic products following patent expiry.
• Clinical Research: Employed as a reference standard in analytical laboratories and pharmaceutical R&D.
• Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for finished dosage form production.
