Chemical Structure
Description
CATO supplies 4-(3,4-Dimethoxyphenyl)-5-ethyl-1,2-dihydro-3h-pyrazol-3-imine (CAS 593279-05-1), a certified reference material (molecular formula C13H17N3O2, MW 247.29 g/mol) for analytical method development and quality control.
4-(3,4-Dimethoxyphenyl)-5-ethyl-1,2-dihydro-3h-pyrazol-3-imine (C13H17N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 4-(3,4-Dimethoxyphenyl)-5-ethyl-1,2-dihydro-3h-pyrazol-3-imine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
