Chemical Structure
Description
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.
3-Isopropyl-4,4-dimethyl-4,5-dihydro-1H-pyrazole-1-carbothioamide (CAS 438541-85-6), molecular formula C9H17N3S and molecular weight 199.32 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, sulfur-containing functionality, 3-Isopropyl-4,4-dimethyl-4,5-dihydro-1H-pyrazole-1-carbothioamide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 199.32 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).
CATO manufactures 3-Isopropyl-4,4-dimethyl-4,5-dihydro-1H-pyrazole-1-carbothioamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
