Chemical Structure
Description
The occurrence of 1-(2-Ethyl-3-methyltetrahydropyrimidin-1(2H)-yl)ethanone is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(2-Ethyl-3-methyltetrahydropyrimidin-1(2H)-yl)ethanone (CAS 191990-65-5), a certified reference material (molecular formula C9H18N2O, MW 170.25 g/mol) for analytical method development and quality control.
The molecular framework of 1-(2-Ethyl-3-methyltetrahydropyrimidin-1(2H)-yl)ethanone (C9H18N2O) is characterized by 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.
