Methyl picolinate is an organic compound with the molecular formula C7H7NO2. It is a methyl ester derivative of picolinic acid, featuring a pyridine ring substituted with a methoxycarbonyl group at the 2-position. This structure makes it a versatile heterocyclic building block. Its primary application is in organic synthesis, particularly as a key intermediate in the preparation of agrochemicals and pharmaceuticals. It serves as a crucial precursor for the synthesis of various picolinamide and pyridine-based compounds. For instance, it is a known intermediate in the production of certain insecticides and fungicides. The ester group is amenable to hydrolysis, transesterification, or aminolysis, allowing for the introduction of diverse functional groups onto the pyridine core. As a liquid with moderate boiling point, it is handled as a standard organic reagent in laboratory settings. It is important to note that, like many pyridine derivatives, it may have an unpleasant odor and should be used with adequate ventilation. Its utility stems from its role as a readily modifiable synthon for constructing more complex nitrogen-containing heterocycles.
