Compared with other compounds in its class, the molecular weight of 305.17 g/mol gives 1-Benzyl-3-(4-bromophenyl)urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Benzyl-3-(4-bromophenyl)urea (CAS 13208-62-3), molecular formula C14H13BrN2O and molecular weight 305.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 1-Benzyl-3-(4-bromophenyl)urea is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
