5-Hydroxy-3-(thiophen-2-yl)-5-(trifluoromethyl)-4,5-dihydro-1H-pyrazole-1-carbothioamide CAS 345923-59-3

Description

As a certified reference material (CRM), 5-Hydroxy-3-(thiophen-2-yl)-5-(trifluoromethyl)-4,5-dihydro-1H-pyrazole-1-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.

5-Hydroxy-3-(thiophen-2-yl)-5-(trifluoromethyl)-4,5-dihydro-1H-pyrazole-1-carbothioamide (CAS 345923-59-3) is a high-purity analytical reference standard with the molecular formula C9H8F3N3OS2 and a molecular weight of 295.30 g/mol.

The molecular framework of 5-Hydroxy-3-(thiophen-2-yl)-5-(trifluoromethyl)-4,5-dihydro-1H-pyrazole-1-carbothioamide (C9H8F3N3OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. 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. 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.
