Chemical Structure
Description
The occurrence of (S)-6-Methyl-5-(quinolin-3-yl)-8,9-dihydropyrimido[5,4-b]indolizine-4,8-diamine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (S)-6-Methyl-5-(quinolin-3-yl)-8,9-dihydropyrimido[5,4-b]indolizine-4,8-diamine (CAS 1661855-22-6), a certified reference material (molecular formula C20H18N6, MW 342.40 g/mol) for analytical method development and quality control.
The molecular framework of (S)-6-Methyl-5-(quinolin-3-yl)-8,9-dihydropyrimido[5,4-b]indolizine-4,8-diamine (C20H18N6) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).
