Description

(6R,7S)-Cefodizime CAS NO 120533-29-1 is a third-generation cephalosporin antibiotic, specifically a stereoisomer of cefodizime. This compound is valued for its potent antibacterial activity against a broad spectrum of Gram-positive and Gram-negative bacteria, including β-lactamase-producing strains. It is primarily utilized in pharmaceutical research and development for creating advanced antibacterial formulations and serves as a critical reference standard for quality control in antibiotic manufacturing.

Application

• Pharmaceutical Active Ingredient (API): Serves as a key intermediate or active component in the synthesis of advanced cephalosporin antibiotic formulations.
• Reference Standard: Used as a high-purity chemical standard in analytical laboratories for quality control, method validation, and regulatory compliance testing of cefodizime-based drugs.
• Biomedical Research: Employed in microbiological and pharmacological studies to investigate mechanisms of action, resistance patterns, and efficacy against resistant bacterial strains.
• Antibiotic Development: Acts as a crucial building block in R&D for developing new antibiotic derivatives with improved pharmacokinetic profiles or spectrum of activity.

Quality Control

Our (6R,7S)-Cefodizime is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets high-grade standards suitable for pharmaceutical research. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere conditions.
