Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-((1-Ethyl-1H-pyrazol-4-yl)methyl)-2-mercapto-4-((1-methyl-1H-pyrazol-4-yl)methylene)-1H-imidazol-5(4H)-one (CAS 1005683-41-9), molecular formula C14H16N6OS and molecular weight 316.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-((1-Ethyl-1H-pyrazol-4-yl)methyl)-2-mercapto-4-((1-methyl-1H-pyrazol-4-yl)methylene)-1H-imidazol-5(4H)-one (C14H16N6OS) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 1-((1-Ethyl-1H-pyrazol-4-yl)methyl)-2-mercapto-4-((1-methyl-1H-pyrazol-4-yl)methylene)-1H-imidazol-5(4H)-one 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.
