4-[3-(2-Chlorophenyl)-1,5-dihydro-5-thioxo-4H-1,2,4-triazol-4-yl]-1,2-dihydro-1,5-dimethyl-2-phenyl-3H-pyrazol-3-one CAS 722464-23-5

Description

As a certified reference material (CRM), 4-[3-(2-Chlorophenyl)-1,5-dihydro-5-thioxo-4H-1,2,4-triazol-4-yl]-1,2-dihydro-1,5-dimethyl-2-phenyl-3H-pyrazol-3-one 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 4-[3-(2-Chlorophenyl)-1,5-dihydro-5-thioxo-4H-1,2,4-triazol-4-yl]-1,2-dihydro-1,5-dimethyl-2-phenyl-3H-pyrazol-3-one (CAS 722464-23-5), a certified reference material (molecular formula C19H16ClN5OS, MW 397.88 g/mol) for analytical method development and quality control.

4-[3-(2-Chlorophenyl)-1,5-dihydro-5-thioxo-4H-1,2,4-triazol-4-yl]-1,2-dihydro-1,5-dimethyl-2-phenyl-3H-pyrazol-3-one (C19H16ClN5OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.
