Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 432.26 g/mol gives 1-Ethyl-2-(3-nitrostyryl)quinolin-1-ium iodide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Ethyl-2-(3-nitrostyryl)quinolin-1-ium iodide (CAS 57755-74-5) is a high-purity analytical reference standard with the molecular formula C19H17N2O2I and a molecular weight of 432.26 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, 1-Ethyl-2-(3-nitrostyryl)quinolin-1-ium iodide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
