Chemical Structure
Description
The occurrence of N-(2-bromophenyl)-2-((3-ethyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N-(2-bromophenyl)-2-((3-ethyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetamide (CAS 329929-13-7), a certified reference material (molecular formula C18H16BrN3O2S, MW 418.31 g/mol) for analytical method development and quality control.
N-(2-bromophenyl)-2-((3-ethyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetamide (C18H16BrN3O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures N-(2-bromophenyl)-2-((3-ethyl-4-oxo-3,4-dihydroquinazolin-2-yl)thio)acetamide 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.
