Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 204.61 g/mol gives 6-Chloro-2-oxo-1,2-dihydroquinoline-3-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Chloro-2-oxo-1,2-dihydroquinoline-3-carbonitrile (CAS 94856-52-7) is a high-purity analytical reference standard with the molecular formula C10H5ClN2O and a molecular weight of 204.61 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloro-2-oxo-1,2-dihydroquinoline-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 204.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
