Chemical Structure

1-(3-Chlorophenyl)-3-(pyrimidin-2-yl)urea CAS 23656-36-2 chemical structure

Description

The occurrence of 1-(3-Chlorophenyl)-3-(pyrimidin-2-yl)urea is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(3-Chlorophenyl)-3-(pyrimidin-2-yl)urea (CAS 23656-36-2) is a high-purity analytical reference standard with the molecular formula C11H9ClN4O and a molecular weight of 248.67 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(3-Chlorophenyl)-3-(pyrimidin-2-yl)urea is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 248.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
