Chemical Structure
Description
The occurrence of 37041-32-0 Ethyl 1-chloro-5-methyl-1,2-dihydroquinoxaline-2-carboxylate DTXSID90747896 is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 37041-32-0 Ethyl 1-chloro-5-methyl-1,2-dihydroquinoxaline-2-carboxylate DTXSID90747896 (CAS 37041-32-0), a certified reference material (molecular formula C13H22ClNO2, MW 259.77 g/mol) for analytical method development and quality control.
37041-32-0 Ethyl 1-chloro-5-methyl-1,2-dihydroquinoxaline-2-carboxylate DTXSID90747896 (C13H22ClNO2) contains an amide group, a carboxylic acid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
