Description
CATO manufactures 2,3-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.
2,3-Dimethylphenyl isothiocyanate (CAS 1539-20-4), molecular formula C9H9NS and molecular weight 163.24 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Dimethylphenyl isothiocyanate (C9H9NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
