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 6,7-Dimethoxy-1-methyl-1,4-dihydroindeno[1,2-c]pyrazole-3-carboxylic acid (CAS 1146292-94-5), a certified reference material (molecular formula C14H14N2O4, MW 274.27 g/mol) for analytical method development and quality control.
Based on its molecular formula C14H14N2O4, 6,7-Dimethoxy-1-methyl-1,4-dihydroindeno[1,2-c]pyrazole-3-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 274.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 6,7-Dimethoxy-1-methyl-1,4-dihydroindeno[1,2-c]pyrazole-3-carboxylic acid 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.
