Chemical Structure
Description
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.
5-Bromo-3-[2-(ethanesulfonyl)ethyl]-3,4-dihydropyrimidin-4-one (CAS 1538097-29-8) is a high-purity analytical reference standard with the molecular formula C8H11BrN2O3S and a molecular weight of 295.15 g/mol.
Based on its molecular formula C8H11BrN2O3S, 5-Bromo-3-[2-(ethanesulfonyl)ethyl]-3,4-dihydropyrimidin-4-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 295.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
