Description

(7S)-7-[[(R)-5-Amino-5-carboxy-1-oxopentyl]amino]-7-methoxy-3-[[[6-amino-3-hydroxy-4-(L-seryl-L-ornithyl-L-valyl-L-ornithyl-L-valylamino)-1,6-dioxohexyl]oxy]methyl]cepham-3-ene-4-carboxylic acid is a complex, semi-synthetic cephalosporin derivative with a sophisticated peptide side chain. This compound is of significant interest for its role as a key intermediate or precursor in the research and development of advanced β-lactam antibiotics. It is primarily utilized by pharmaceutical R&D teams and fine chemical manufacturers focused on novel antimicrobial agents and structure-activity relationship (SAR) studies. The intricate structure offers a valuable scaffold for exploring new mechanisms of action against resistant bacterial strains.

Application

• Pharmaceutical Intermediate: Critical precursor in the synthesis of novel cephalosporin-class antibiotics for research and development.
• Antimicrobial Research: Used as a reference standard or building block in SAR studies to develop new agents against drug-resistant bacteria.
• Biochemical Research: Serves as a substrate or inhibitor in enzymatic studies related to bacterial cell wall synthesis and β-lactamase activity.
• Fine Chemical Synthesis: Employed in custom synthesis and contract manufacturing for specialized, high-value pharmaceutical projects.
• Academic Research: Utilized in university and institutional labs for studies in medicinal chemistry and antibiotic discovery.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as purity, identity, and impurity profiles. We adhere to GMP (Good Manufacturing Practice) guidelines for the handling of advanced pharmaceutical intermediates, ensuring traceability and batch-to-batch consistency suitable for research and development applications.

Storage

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