Description
CATO supplies 2-Bromopyridine-4-carbothioamide (CAS 4502-23-2), a certified reference material (molecular formula C6H5BrN2S, MW 217.09 g/mol) for analytical method development and quality control.
2-Bromopyridine-4-carbothioamide (C6H5BrN2S) contains a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 2-Bromopyridine-4-carbothioamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
