Chemical Structure
Description
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.
CATO supplies Methyl 3-isobutyl-2-mercapto-4-oxo-3,4-dihydroquinazoline-7-carboxylate (CAS 855715-37-6), a certified reference material (molecular formula C14H16N2O3S, MW 292.35 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-isobutyl-2-mercapto-4-oxo-3,4-dihydroquinazoline-7-carboxylate (C14H16N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
