1-(3,4-Dichlorophenyl)-3-(4-(pyridin-4-ylmethyl)phenyl)urea CAS 669757-93-1

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.

CATO supplies 1-(3,4-Dichlorophenyl)-3-(4-(pyridin-4-ylmethyl)phenyl)urea (CAS 669757-93-1), a certified reference material (molecular formula C19H15Cl2N3O, MW 372.25 g/mol) for analytical method development and quality control.

The molecular framework of 1-(3,4-Dichlorophenyl)-3-(4-(pyridin-4-ylmethyl)phenyl)urea (C19H15Cl2N3O) is characterized by a steroid core, 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.

CATO manufactures 1-(3,4-Dichlorophenyl)-3-(4-(pyridin-4-ylmethyl)phenyl)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.
