Chemical Structure
Description
(E)-Ethyl 3-(2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)acrylate (CAS 55520-60-0) is a high-purity analytical reference standard with the molecular formula C9H10N2O4 and a molecular weight of 210.19 g/mol.
The molecular framework of (E)-Ethyl 3-(2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)acrylate (C9H10N2O4) is characterized by an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), (E)-Ethyl 3-(2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl)acrylate 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.
