Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 372.29 g/mol gives 2-(4-Butylphenyl)-7-chloro-8-methylquinoline-4-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(4-Butylphenyl)-7-chloro-8-methylquinoline-4-carbonyl chloride (CAS 1160256-30-3), a certified reference material (molecular formula C21H19Cl2NO, MW 372.29 g/mol) for analytical method development and quality control.
2-(4-Butylphenyl)-7-chloro-8-methylquinoline-4-carbonyl chloride (C21H19Cl2NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
