Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3E)-5-bromo-3-[(2,4-difluorophenyl)imino]-2,3-dihydro-1H-indol-2-one 118416-28-7 MS-8800.
CATO supplies (3E)-5-bromo-3-[(2,4-difluorophenyl)imino]-2,3-dihydro-1H-indol-2-one 118416-28-7 MS-8800 (CAS 118416-28-7), a certified reference material (molecular formula C14H7BrF2N2O, MW 337.12 g/mol) for analytical method development and quality control.
(3E)-5-bromo-3-[(2,4-difluorophenyl)imino]-2,3-dihydro-1H-indol-2-one 118416-28-7 MS-8800 (C14H7BrF2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
