Chemical Structure

5,8-Difluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid CAS 797052-45-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,8-Difluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid.

CATO supplies 5,8-Difluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (CAS 797052-45-0), a certified reference material (molecular formula C10H5F2NO3, MW 225.15 g/mol) for analytical method development and quality control.

Structurally, 5,8-Difluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (C10H5F2NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 225.15 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
