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.

1-Methyl-N-(3-methylisothiazol-5-yl)-3-phenyl-1H-pyrazole-5-carboxamide (CAS 1219913-07-1), molecular formula C15H14N4OS and molecular weight 298.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Methyl-N-(3-methylisothiazol-5-yl)-3-phenyl-1H-pyrazole-5-carboxamide (C15H14N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.

CATO manufactures 1-Methyl-N-(3-methylisothiazol-5-yl)-3-phenyl-1H-pyrazole-5-carboxamide 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.
