Chemical Structure

3-Phenyl-1-(pyridin-4-yl)urea CAS 1932-35-0 chemical structure

Description

3-Phenyl-1-(pyridin-4-yl)urea (CAS 1932-35-0) is a high-purity analytical reference standard with the molecular formula C12H11N3O and a molecular weight of 213.24 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3-Phenyl-1-(pyridin-4-yl)urea is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 213.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures 3-Phenyl-1-(pyridin-4-yl)urea under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
