Chemical Structure
Description
The occurrence of ethyl 4-chloro-5-methyl-7-prop-1-ynyl-quinoline-3-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
ethyl 4-chloro-5-methyl-7-prop-1-ynyl-quinoline-3-carboxylate (CAS 2623407-29-2), molecular formula C16H14ClNO2 and molecular weight 287.74 g/mol, is a CATO reference standard with documented purity and traceability.
ethyl 4-chloro-5-methyl-7-prop-1-ynyl-quinoline-3-carboxylate (C16H14ClNO2) contains a nitrogen-containing heterocyclic scaffold, 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), ethyl 4-chloro-5-methyl-7-prop-1-ynyl-quinoline-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
