1-Ethyl-2-((E)-3-((E)-1-ethylquinolin-2(1H)-ylidene)prop-1-en-1-yl)quinolin-1-ium bromide CAS 2670-67-9

Description

The occurrence of 1-Ethyl-2-((E)-3-((E)-1-ethylquinolin-2(1H)-ylidene)prop-1-en-1-yl)quinolin-1-ium bromide is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Ethyl-2-((E)-3-((E)-1-ethylquinolin-2(1H)-ylidene)prop-1-en-1-yl)quinolin-1-ium bromide (CAS 2670-67-9) is a high-purity analytical reference standard with the molecular formula C25H25N2Br and a molecular weight of 433.39 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 1-Ethyl-2-((E)-3-((E)-1-ethylquinolin-2(1H)-ylidene)prop-1-en-1-yl)quinolin-1-ium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 433.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
