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 (Z)-4-Benzylidene-2-(2-bromophenyl)oxazol-5(4H)-one.
CATO supplies (Z)-4-Benzylidene-2-(2-bromophenyl)oxazol-5(4H)-one (CAS 849770-51-0), a certified reference material (molecular formula C16H10BrNO2, MW 328.16 g/mol) for analytical method development and quality control.
(Z)-4-Benzylidene-2-(2-bromophenyl)oxazol-5(4H)-one (C16H10BrNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 (Z)-4-Benzylidene-2-(2-bromophenyl)oxazol-5(4H)-one 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.
