The occurrence of 1-(4-chloro-3-(trifluoromethyl)phenyl)-3-((3-(4-fluorophenyl)-4-oxoquinazolin-2-yl)methyl)urea is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(4-chloro-3-(trifluoromethyl)phenyl)-3-((3-(4-fluorophenyl)-4-oxoquinazolin-2-yl)methyl)urea (CAS 330796-24-2), molecular formula C23H33ClF4N4O2 and molecular weight 508.98 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 1-(4-chloro-3-(trifluoromethyl)phenyl)-3-((3-(4-fluorophenyl)-4-oxoquinazolin-2-yl)methyl)urea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 508.98 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 1-(4-chloro-3-(trifluoromethyl)phenyl)-3-((3-(4-fluorophenyl)-4-oxoquinazolin-2-yl)methyl)urea 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.
