Chemical Structure
Description
The occurrence of 2-(5-Chloro-2-thienyl)-6,8-dimethylquinoline-4-carbonyl chloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(5-Chloro-2-thienyl)-6,8-dimethylquinoline-4-carbonyl chloride (CAS 1160254-85-2) is a high-purity analytical reference standard with the molecular formula C16H11Cl2NOS and a molecular weight of 336.24 g/mol.
Based on its molecular formula C16H11Cl2NOS, 2-(5-Chloro-2-thienyl)-6,8-dimethylquinoline-4-carbonyl chloride contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 336.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
