1-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-3-methyl-5-[(2E)-3-{[4-(trifluoromethyl)phenyl]amino}prop-2-enoyl]-1,2,3,4-tetrahydropyrimidine-2,4-dione (CAS 338770-35-7) is a high-purity analytical reference standard with the molecular formula C23H18ClF6N5O3 and a molecular weight of 561.86 g/mol.
The molecular framework of 1-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-3-methyl-5-[(2E)-3-{[4-(trifluoromethyl)phenyl]amino}prop-2-enoyl]-1,2,3,4-tetrahydropyrimidine-2,4-dione (C23H18ClF6N5O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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 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).
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), 1-(2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}ethyl)-3-methyl-5-[(2E)-3-{[4-(trifluoromethyl)phenyl]amino}prop-2-enoyl]-1,2,3,4-tetrahydropyrimidine-2,4-dione 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.
