Chemical Structure
Description
As a certified reference material (CRM), 5-chloro-thiazole-2-carbonitrile 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.
CATO supplies 5-chloro-thiazole-2-carbonitrile (CAS 98020-94-1), a certified reference material (molecular formula C4H5ClN2S, MW 148.61 g/mol) for analytical method development and quality control.
5-chloro-thiazole-2-carbonitrile (C4H5ClN2S) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
