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 Methyl 2-[8-bromo-6-methyl-4-oxo-2-(trifluoromethyl)-3,4-dihydroquinazolin-3-yl]acetate.
Methyl 2-[8-bromo-6-methyl-4-oxo-2-(trifluoromethyl)-3,4-dihydroquinazolin-3-yl]acetate (CAS 866151-16-8), molecular formula C13H10BrF3N2O3 and molecular weight 379.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 2-[8-bromo-6-methyl-4-oxo-2-(trifluoromethyl)-3,4-dihydroquinazolin-3-yl]acetate (C13H10BrF3N2O3) 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. 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.
