Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies ethyl (2Z)-(3,5-dimethyl-1-phenyl-1H-pyrazol-4-yl)(hydroxyimino)acetate (CAS 1006444-16-1), a certified reference material (molecular formula C15H17N3O3, MW 287.31 g/mol) for analytical method development and quality control.
The molecular framework of ethyl (2Z)-(3,5-dimethyl-1-phenyl-1H-pyrazol-4-yl)(hydroxyimino)acetate (C15H17N3O3) 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).
CATO manufactures ethyl (2Z)-(3,5-dimethyl-1-phenyl-1H-pyrazol-4-yl)(hydroxyimino)acetate 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.
