Chemical Structure
Description
CATO manufactures 3-Methyl-4-(2-methylbutylidene)-1H-pyrazol-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.
CATO supplies 3-Methyl-4-(2-methylbutylidene)-1H-pyrazol-5(4H)-one (CAS 834898-55-4), a certified reference material (molecular formula C9H14N2O, MW 166.22 g/mol) for analytical method development and quality control.
The molecular framework of 3-Methyl-4-(2-methylbutylidene)-1H-pyrazol-5(4H)-one (C9H14N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
