Chemical Structure
Description
2-(4-Bromo-3,5-dimethyl-1H-pyrazol-1-yl)ethanethioamide (CAS 175202-68-3), molecular formula C7H10BrN3S and molecular weight 248.14 g/mol, is a CATO reference standard with documented purity and traceability.
2-(4-Bromo-3,5-dimethyl-1H-pyrazol-1-yl)ethanethioamide (C7H10BrN3S) contains a nitrile group, sulfur-containing functionality, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures 2-(4-Bromo-3,5-dimethyl-1H-pyrazol-1-yl)ethanethioamide 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.
