Chemical Structure

5-(3,4-Dimethoxyphenyl)-3-phenyl-4,5-dihydro-1H-pyrazole-1-carbothioamide CAS 1032469-60-5 chemical structure

Description

The occurrence of 5-(3,4-Dimethoxyphenyl)-3-phenyl-4,5-dihydro-1H-pyrazole-1-carbothioamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(3,4-Dimethoxyphenyl)-3-phenyl-4,5-dihydro-1H-pyrazole-1-carbothioamide (CAS 1032469-60-5) is a high-purity analytical reference standard with the molecular formula C18H19N3O2S and a molecular weight of 341.43 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-(3,4-Dimethoxyphenyl)-3-phenyl-4,5-dihydro-1H-pyrazole-1-carbothioamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 341.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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), 5-(3,4-Dimethoxyphenyl)-3-phenyl-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.
