Description

Staphylomycin S3 is a potent antibiotic compound belonging to the streptogramin family, identified by CAS No. 33477-39-3. It serves as a critical component in the research and development of novel antimicrobial agents, particularly against Gram-positive bacteria. This product is essential for pharmaceutical R&D laboratories, academic research institutions, and manufacturers developing veterinary or human therapeutics targeting resistant bacterial strains.

Application

• Pharmaceutical Research & Development: A key intermediate or reference standard in the synthesis and study of new streptogramin-class antibiotics.
• Antimicrobial Mechanism Studies: Used in biochemical and microbiological research to investigate bacterial protein synthesis inhibition and synergy with other streptogramins.
• Veterinary Medicine Development: Employed in formulating or researching treatments for bacterial infections in animals.
• Microbiology & Diagnostics: Acts as a selective agent in culture media or as a standard in assays for determining bacterial susceptibility.
• Biochemical Reagent: Serves as a high-purity reagent in enzymatic studies and molecular biology research related to ribosomal function.
• Reference Material Production: Used by manufacturers to produce certified reference standards for quality control in antibiotic production.

Quality Control

Our Staphylomycin S3 is produced and tested under strict quality management systems to ensure high purity and batch-to-batch consistency. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry guidelines for research-grade materials to support your critical applications.

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. For long-term storage, consider desiccants or inert atmosphere.
