Description
CATO manufactures 5-Bromo-7-fluoro-2,3-dihydro-1h-indole-2,3-dione 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.
CATO supplies 5-Bromo-7-fluoro-2,3-dihydro-1h-indole-2,3-dione (CAS 874830-75-8), a certified reference material (molecular formula C8H3BrFNO2, MW 244.02 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-7-fluoro-2,3-dihydro-1h-indole-2,3-dione (C8H3BrFNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine 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. 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.
