4-(5-Ethyl-1,2,4-oxadiazol-3-yl)-2-{[3-(trifluoromethyl)phenyl]methyl}-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidine-1,3-dione CAS 1775402-65-7

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO supplies 4-(5-Ethyl-1,2,4-oxadiazol-3-yl)-2-{[3-(trifluoromethyl)phenyl]methyl}-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidine-1,3-dione (CAS 1775402-65-7), a certified reference material (molecular formula C20H19F3N4O3, MW 420.39 g/mol) for analytical method development and quality control.

The molecular framework of 4-(5-Ethyl-1,2,4-oxadiazol-3-yl)-2-{[3-(trifluoromethyl)phenyl]methyl}-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidine-1,3-dione (C20H19F3N4O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 4-(5-Ethyl-1,2,4-oxadiazol-3-yl)-2-{[3-(trifluoromethyl)phenyl]methyl}-1H,2H,3H,5H,6H,7H,8H-pyrido[1,2-c]pyrimidine-1,3-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.
