Description

3-Quinolinecarboxylic Acid, 1-Cyclopropyl-7-(4-Ethyl-1-Piperazinyl)-6-Fluoro-1,4-Dihydro-4-Oxo-, 2-Oxo-2-(Propylamino)Ethyl Ester is a high-purity, complex heterocyclic compound designed for advanced pharmaceutical research and development. This molecule serves as a critical pharmaceutical intermediate, offering a sophisticated scaffold for the synthesis of novel active pharmaceutical ingredients (APIs). It is primarily targeted at pharmaceutical manufacturers and contract research organizations (CROs) engaged in the discovery and production of next-generation therapeutics.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel fluoroquinolone-class antibiotics and other advanced antimicrobial agents.
• Active Pharmaceutical Ingredient (API) Development: Serves as a core structural component for developing new chemical entities (NCEs) targeting bacterial infections.
• Research & Development: Used in medicinal chemistry for structure-activity relationship (SAR) studies and lead optimization in drug discovery pipelines.
• Preclinical Studies: Essential material for formulating drug candidates for in-vitro and in-vivo efficacy and safety testing.
• Process Chemistry: Employed in scaling up synthetic routes from laboratory to pilot plant and commercial manufacturing scales.
• Reference Standard: High-purity grade suitable for use as an analytical reference standard in quality control laboratories.
