Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 333.21 g/mol gives 8-Ethyl-2-(pyridin-3-yl)quinoline-4-carbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
8-Ethyl-2-(pyridin-3-yl)quinoline-4-carbonyl chloride (CAS 1203127-15-4), molecular formula C17H13ClN2OHCl and molecular weight 333.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 8-Ethyl-2-(pyridin-3-yl)quinoline-4-carbonyl chloride (C17H13ClN2OHCl) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
