Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-(2-(5-Cyclopropyl-3-(pyridin-4-yl)-1H-pyrazol-1-yl)ethyl)-3-phenylurea (CAS 1797294-32-6), molecular formula C20H21N5O and molecular weight 347.41 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2-(5-Cyclopropyl-3-(pyridin-4-yl)-1H-pyrazol-1-yl)ethyl)-3-phenylurea (C20H21N5O) is characterized by a steroid core, 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).
As a certified reference material (CRM), 1-(2-(5-Cyclopropyl-3-(pyridin-4-yl)-1H-pyrazol-1-yl)ethyl)-3-phenylurea 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.
