7-(3-Aminopyrrolidin-1-yl)-1-cyclopropyl-8-ethoxy-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid CAS 182868-77-5 chemical structure

Description

7-(3-Aminopyrrolidin-1-yl)-1-cyclopropyl-8-ethoxy-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (CAS 182868-77-5), molecular formula C19H22FN3O4 and molecular weight 375.39 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-(3-Aminopyrrolidin-1-yl)-1-cyclopropyl-8-ethoxy-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (C19H22FN3O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 7-(3-Aminopyrrolidin-1-yl)-1-cyclopropyl-8-ethoxy-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
