Description

Cephalexin Ethyl Homolog CAS NO 36114-06-4 is a key chemical intermediate and reference standard in the synthesis and analytical verification of β-lactam antibiotics. This compound matters for its critical role in pharmaceutical research and development, enabling the production and quality control of advanced cephalosporin-based drugs. It is primarily needed by manufacturers and R&D laboratories in the pharmaceutical, biotechnology, and fine chemical sectors focused on antibiotic development and analytical chemistry.

Application

• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of novel cephalosporin antibiotic derivatives.
• Reference Standard: Used in analytical laboratories for method development, validation, and quality control testing of cephalexin and related compounds via HPLC, LC-MS, or other chromatographic techniques.
• Research & Development: Employed in medicinal chemistry programs to study structure-activity relationships (SAR) and develop new antibacterial agents.
• Impurity Standard: Acts as a certified reference material (CRM) for identifying and quantifying specified impurities in cephalexin active pharmaceutical ingredient (API) batches to meet pharmacopeial standards (e.g., USP, EP).
• Process Chemistry: Utilized in scaling up and optimizing manufacturing processes for β-lactam antibiotics.

Quality Control

Our Cephalexin Ethyl Homolog is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets the high standards required for pharmaceutical research and development. Certificates of Analysis (COA) with detailed chromatographic data are provided for 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.
