Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 391.26 g/mol gives 2-(3-Bromophenoxy)-N-(4-morpholinophenyl)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(3-Bromophenoxy)-N-(4-morpholinophenyl)acetamide (CAS 302805-52-3), molecular formula C18H19BrN2O3 and molecular weight 391.26 g/mol, is a CATO reference standard with documented purity and traceability.
2-(3-Bromophenoxy)-N-(4-morpholinophenyl)acetamide (C18H19BrN2O3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
