Chemical Structure
Description
The molecular framework of 1,3-Dimethyl 5-{2-[4-(pyrimidin-2-yl)piperazin-1-yl]acetamido}benzene-1,3-dicarboxylate (C20H23N5O5) is characterized by a flavonoid 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).
1,3-Dimethyl 5-{2-[4-(pyrimidin-2-yl)piperazin-1-yl]acetamido}benzene-1,3-dicarboxylate (CAS 896216-09-4), molecular formula C20H23N5O5 and molecular weight 413.43 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
