Description
Compared with other compounds in its class, the molecular weight of 387.23 g/mol gives 2-Bromo-N-(4-(2-carbamoylphenoxy)but-2-yn-1-yl)benzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Bromo-N-(4-(2-carbamoylphenoxy)but-2-yn-1-yl)benzamide (CAS 1421481-49-3), a certified reference material (molecular formula C18H15BrN2O3, MW 387.23 g/mol) for analytical method development and quality control.
2-Bromo-N-(4-(2-carbamoylphenoxy)but-2-yn-1-yl)benzamide (C18H15BrN2O3) contains a steroid core, an amide 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.
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.
