Description

Phenethicillin Sodium Salt CAS NO 30302-52-4 is a semisynthetic penicillin antibiotic derived from 6-aminopenicillanic acid. This compound is valued for its stability and efficacy against a range of Gram-positive bacteria. It is primarily utilized in pharmaceutical research and development, serving as a key intermediate or reference standard for antimicrobial studies and quality control in antibiotic manufacturing.

Application

• Pharmaceutical intermediate for the synthesis of penicillin-based antibiotic formulations.
• Reference standard in analytical laboratories for quality control and method validation (HPLC, LC-MS).
• Active Pharmaceutical Ingredient (API) research for studying structure-activity relationships in β-lactam antibiotics.
• Microbiological research to investigate bacterial resistance mechanisms and antimicrobial efficacy.
• Preparation of laboratory-grade reagents for in-vitro diagnostic and biochemical assays.

Quality Control

Our Phenethicillin Sodium Salt is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets high-grade standards suitable for research and development. A Certificate of Analysis (COA) detailing specific results for each parameter is provided with every shipment.

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