Chemical Structure
Description
Ethyl 6-chloro-4-methylnicotinate (C9H10ClNO2) 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, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Ethyl 6-chloro-4-methylnicotinate (CAS 57591-95-4), molecular formula C9H10ClNO2 and molecular weight 199.63 g/mol, is a CATO reference standard with documented purity and traceability.
