Description

Cefprozil (Z)-Isomer (200 Mg) is a high-purity, stereochemically defined isomer of the broad-spectrum cephalosporin antibiotic, Cefprozil. This specific isomer is critical for pharmaceutical research and development, particularly in the study of structure-activity relationships, metabolic pathways, and the synthesis of advanced intermediates. It is an essential reference standard and building block for analytical laboratories, academic institutions, and R&D departments within the global pharmaceutical and biotechnology industries focused on antibiotic development and quality control.

Application

• Pharmaceutical Reference Standard: Used as a certified reference material (CRM) for the identification, assay, and impurity profiling of Cefprozil in quality control laboratories.
• Active Pharmaceutical Ingredient (API) Research: Serves as a key intermediate or starting material in the research and development of novel cephalosporin-based antibiotics.
• Analytical Method Development: Employed for developing and validating chromatographic (HPLC, UPLC) and spectroscopic methods to separate and quantify Cefprozil isomers.
• Metabolic and Pharmacokinetic Studies: Utilized in preclinical research to investigate the absorption, distribution, metabolism, and excretion (ADME) profiles of specific Cefprozil stereoisomers.
• Academic and Institutional Research: A vital tool for universities and research institutes conducting studies on antibiotic resistance, synthesis pathways, and medicinal chemistry.

Quality Control

Our Cefprozil (Z)-Isomer is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, chiral methods for isomeric content, and identification via IR and NMR spectroscopy, to ensure it meets high-purity standards suitable for research and development. A detailed Certificate of Analysis (COA) specifying batch-specific results 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 (typically 15-25°C). This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability.
