Chemical Structure
Description
4,7-Dichloro-6-nitroquinoline-3-carbonitrile (CAS 263149-40-2), molecular formula C10H3Cl2N3O2 and molecular weight 268.06 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H3Cl2N3O2, 4,7-Dichloro-6-nitroquinoline-3-carbonitrile contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 268.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
