Chemical Structure
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-(2,4-Difluorophenyl)-2-thiourea (CAS 175277-76-6), a certified reference material (molecular formula C7H6F2N2S, MW 188.20 g/mol) for analytical method development and quality control.
The molecular framework of 1-(2,4-Difluorophenyl)-2-thiourea (C7H6F2N2S) is characterized by a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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-(2,4-Difluorophenyl)-2-thiourea 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.
