Description

Cefoselis CAS NO 12284-10-5 is a fourth-generation cephalosporin antibiotic belonging to the β-lactam class. This compound is valued for its broad-spectrum activity against both Gram-positive and Gram-negative bacteria, including strains resistant to earlier-generation cephalosporins. It is primarily utilized in the pharmaceutical industry for the research, development, and synthesis of advanced injectable antibiotic formulations.

Application

• Pharmaceutical Active Ingredient (API): Primary use in the formulation of injectable antibiotic drugs for clinical use.
• Antibacterial Research: A key reference standard and intermediate in microbiological and pharmacological research studies.
• Veterinary Medicine: Development of antibacterial treatments for veterinary applications.
• Hospital-Acquired Infection Treatment: Research into formulations targeting multi-drug resistant infections prevalent in hospital settings.
• Chemical Synthesis Intermediate: Serves as a crucial building block in the synthesis of more complex cephalosporin derivatives.
• Quality Control Standard: Used as a certified reference material (CRM) in analytical laboratories for assay and impurity testing.

Quality Control

Our Cefoselis is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and related substances, to ensure it meets high-grade pharmaceutical standards. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request.

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 dry environment to prevent moisture absorption.
