Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-(3,4-Dichlorophenyl)-3-(pyridin-3-yl)urea (CAS 13142-48-8), a certified reference material (molecular formula C12H9Cl2N3O, MW 282.13 g/mol) for analytical method development and quality control.
The molecular framework of 1-(3,4-Dichlorophenyl)-3-(pyridin-3-yl)urea (C12H9Cl2N3O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 1-(3,4-Dichlorophenyl)-3-(pyridin-3-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.
