Chemical Structure
Description
CATO supplies 4-(3,4-Difluorophenyl)thiosemicarbazide (CAS 848079-92-5), a certified reference material (molecular formula C7H7F2N3S, MW 203.21 g/mol) for analytical method development and quality control.
The molecular framework of 4-(3,4-Difluorophenyl)thiosemicarbazide (C7H7F2N3S) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-(3,4-Difluorophenyl)thiosemicarbazide 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.
