Chemical Structure
Description
1-Ethyl-4-(5-(1-ethylquinolin-4(1H)-ylidene)penta-1,3-dien-1-yl)quinolin-1-ium iodide (CAS 18300-31-7) is a high-purity analytical reference standard with the molecular formula C27H27N2I and a molecular weight of 506.43 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution, 1-Ethyl-4-(5-(1-ethylquinolin-4(1H)-ylidene)penta-1,3-dien-1-yl)quinolin-1-ium iodide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 506.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Ethyl-4-(5-(1-ethylquinolin-4(1H)-ylidene)penta-1,3-dien-1-yl)quinolin-1-ium iodide 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.
