Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Bromo-1,4-dihydro-7-fluoro-1-[(1S)-1-(hydroxymethyl)-2-methylpropyl]-4-oxo-3-quinolinecarboxylic Acid Ethyl Ester.
CATO supplies 6-Bromo-1,4-dihydro-7-fluoro-1-[(1S)-1-(hydroxymethyl)-2-methylpropyl]-4-oxo-3-quinolinecarboxylic Acid Ethyl Ester (CAS 934161-50-9), a certified reference material (molecular formula C17H19BrFNO4, MW 400.24 g/mol) for analytical method development and quality control.
Based on its molecular formula C17H19BrFNO4, 6-Bromo-1,4-dihydro-7-fluoro-1-[(1S)-1-(hydroxymethyl)-2-methylpropyl]-4-oxo-3-quinolinecarboxylic Acid Ethyl Ester contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 400.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 6-Bromo-1,4-dihydro-7-fluoro-1-[(1S)-1-(hydroxymethyl)-2-methylpropyl]-4-oxo-3-quinolinecarboxylic Acid Ethyl Ester 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.
