Description

Cefmatilen CAS NO 140128-74-1 is a third-generation cephalosporin antibiotic belonging to the cephem class of compounds. This advanced pharmaceutical intermediate is valued for its broad-spectrum antibacterial activity, particularly against gram-negative bacteria. It is a critical building block for the synthesis of finished active pharmaceutical ingredients (APIs) targeting respiratory and urinary tract infections. Key industries requiring this high-purity compound include pharmaceutical manufacturing, contract research organizations (CROs), and academic research institutions.

Application

• Pharmaceutical API Synthesis: Primary use as a key intermediate in the production of finished cephalosporin antibiotic drugs.
• Antibacterial Research: Serves as a reference standard and starting material in R&D for novel antibiotic formulations and combination therapies.
• Veterinary Medicine: Used in the development of antibacterial treatments for livestock and companion animals.
• Clinical Trial Material: Supplied as a GMP-grade intermediate for the manufacture of drugs undergoing clinical evaluation.
• Chemical Reference Standard: Utilized in analytical laboratories for method development, validation, and quality control testing.

Quality Control

Our Cefmatilen is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, residual solvent analysis, and identification by IR and NMR spectroscopy. We provide full traceability and Certificates of Analysis (COA) that detail all test results against stringent in-house specifications. Production can be aligned with cGMP guidelines for pharmaceutical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under inert conditions or in a desiccator to prevent degradation. Keep away from incompatible materials.
