As a certified reference material (CRM), 3-(Ethoxycarbonyl)-1-(3-methoxyphenyl)-4,5-dihydro-1h-pyrazole-5-carboxylic acid 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.
CATO supplies 3-(Ethoxycarbonyl)-1-(3-methoxyphenyl)-4,5-dihydro-1h-pyrazole-5-carboxylic acid (CAS 1264045-28-4), a certified reference material (molecular formula C14H16N2O5, MW 292.29 g/mol) for analytical method development and quality control.
The molecular framework of 3-(Ethoxycarbonyl)-1-(3-methoxyphenyl)-4,5-dihydro-1h-pyrazole-5-carboxylic acid (C14H16N2O5) 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.
