Description

Compared with other compounds in its class, the molecular weight of 347.35 g/mol gives 1-(2-Fluorophenyl)-3-(3-(imidazo[1,2-a]pyrimidin-2-yl)phenyl)urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(2-Fluorophenyl)-3-(3-(imidazo[1,2-a]pyrimidin-2-yl)phenyl)urea (CAS 861210-37-9) is a high-purity analytical reference standard with the molecular formula C19H14FN5O and a molecular weight of 347.35 g/mol.

1-(2-Fluorophenyl)-3-(3-(imidazo[1,2-a]pyrimidin-2-yl)phenyl)urea (C19H14FN5O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; 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.
