Description

Cefclidin CAS NO 105239-91-6 is a synthetic cephalosporin antibiotic belonging to the advanced generation of β-lactam compounds. It is valued for its potent antibacterial activity, particularly against a broad spectrum of Gram-positive and Gram-negative pathogens. This high-purity pharmaceutical intermediate is essential for research and development laboratories, as well as manufacturers in the fine chemical and active pharmaceutical ingredient (API) sectors.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of advanced cephalosporin antibiotic formulations.
• Antibacterial Research: Used in microbiological and pharmacological studies to investigate mechanisms of action and resistance.
• Reference Standard: Employed as a high-purity standard in analytical laboratories for quality control and method development (HPLC, LC-MS).
• API Development: A critical raw material in the development and scale-up production of novel antibiotic drugs.
• Veterinary Medicine: Potential application in the development of antibacterial treatments for veterinary use.
