1-(2,3-Dichlorophenyl)-3-phenylurea CAS 13142-52-4

Description

Compared with other compounds in its class, the molecular weight of 281.14 g/mol gives 1-(2,3-Dichlorophenyl)-3-phenylurea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(2,3-Dichlorophenyl)-3-phenylurea (CAS 13142-52-4), molecular formula C13H10Cl2N2O and molecular weight 281.14 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(2,3-Dichlorophenyl)-3-phenylurea (C13H10Cl2N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
