Chemical Structure
Description
3,4-Dimethylphenyl isothiocyanate (CAS 19241-17-9), molecular formula C9H9NS and molecular weight 163.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,4-Dimethylphenyl isothiocyanate (C9H9NS) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 3,4-Dimethylphenyl isothiocyanate 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.
