Description

δ2-Cefteram is a third-generation cephalosporin antibiotic intermediate, specifically a cephem derivative. This compound is of critical importance for the synthesis of advanced, broad-spectrum antibiotics used in human and veterinary medicine. It is primarily required by pharmaceutical manufacturers and research institutions engaged in the development and production of next-generation antibacterial agents.

Application

• Pharmaceutical API Synthesis: Key intermediate in the industrial-scale production of the active pharmaceutical ingredient (API) cefteram pivoxil.
• Antibiotic Research & Development: Serves as a crucial building block for medicinal chemists developing novel cephalosporin derivatives with improved efficacy.
• Veterinary Medicine Production: Used in formulating advanced antibacterial treatments for livestock and companion animals.
• Reference Standard: Employed as a high-purity analytical standard in quality control laboratories for HPLC, LC-MS, or NMR method development and validation.
• Process Chemistry: Utilized in optimizing fermentation and semi-synthetic pathways for cephalosporin manufacturing.

Quality Control

Our δ2-Cefteram is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements for pharmaceutical intermediate use. Certificates of Analysis (COA) detailing all specifications and test results are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. Long-term storage under inert atmosphere (e.g., nitrogen) is recommended.
