Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Quinolin-5(4aH)-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.16 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).
CATO supplies Quinolin-5(4aH)-one (CAS 477775-99-8), a certified reference material (molecular formula C9H7NO, MW 145.16 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
