Description

Mecillinam CAS NO 79580-20-4 is a semisynthetic penicillin derivative belonging to the amidinopenicillin class of β-lactam antibiotics. Its primary value lies in its unique mechanism of action, specifically targeting penicillin-binding protein 2 (PBP-2), which provides a distinct antibacterial profile against many Gram-negative bacteria. This compound is a critical active pharmaceutical ingredient (API) and a key intermediate for pharmaceutical manufacturers and research institutions developing antibacterial therapies.

Application

• Active Pharmaceutical Ingredient (API) for the formulation of antibacterial medications.
• Pharmaceutical Intermediate in the synthesis of more complex antibiotic compounds.
• Reference Standard for quality control and analytical testing in pharmaceutical laboratories.
• Research & Development of new antimicrobial agents and for studying bacterial resistance mechanisms.
• Microbiological Studies to evaluate efficacy against specific Gram-negative pathogens.
