Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromo-4-(methylthio)pyridine (CAS 1193244-91-5), molecular formula C6H6BrNS and molecular weight 204.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-4-(methylthio)pyridine (C6H6BrNS) is characterized by a nitrile group, sulfur-containing functionality, bromine 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 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).
CATO manufactures 2-Bromo-4-(methylthio)pyridine 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.
