CATO supplies Ethyl 3-(3,4-dichlorobenzyl)-2-oxo-2,3-dihydro-1H-benzo[d]imidazole-1-carboxylate (CAS 339013-49-9), a certified reference material (molecular formula C17H14Cl2N2O3, MW 365.21 g/mol) for analytical method development and quality control.
Ethyl 3-(3,4-dichlorobenzyl)-2-oxo-2,3-dihydro-1H-benzo[d]imidazole-1-carboxylate (C17H14Cl2N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. 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.
