Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1580AE 35975-71-4 8-Chloro-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid C10H6ClNO3.
CATO supplies 1580AE 35975-71-4 8-Chloro-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid C10H6ClNO3 (CAS 35975-71-4), a certified reference material (molecular formula C10H6ClNO3, MW 223.61 g/mol) for analytical method development and quality control.
Structurally, 1580AE 35975-71-4 8-Chloro-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid C10H6ClNO3 (C10H6ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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 223.61 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 1580AE 35975-71-4 8-Chloro-4-oxo-1,4-dihydro-quinoline-3-carboxylic acid C10H6ClNO3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
