Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(4,6-Dimethylpyrimidin-2-yl)-5-phenyl-4,5-dihydro-1H-pyrazole-1-carboximidamide (CAS 577791-34-5), molecular formula C16H18N6 and molecular weight 294.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(4,6-Dimethylpyrimidin-2-yl)-5-phenyl-4,5-dihydro-1H-pyrazole-1-carboximidamide (C16H18N6) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 N-(4,6-Dimethylpyrimidin-2-yl)-5-phenyl-4,5-dihydro-1H-pyrazole-1-carboximidamide 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.
