Pharmaceutical intermediate
Used as a fluorinated heterocyclic building block in medicinal chemistry and the synthesis of pharmaceutical candidates. The activated 2-fluoro position on the pyridine ring is well suited to nucleophilic aromatic substitution.
Fluorinated building block
Serves as a versatile C7 fluoropyridine scaffold for installing fluorine and a substituted-pyridine motif into more complex target molecules during multi-step synthesis.
Ester handle for further functionalisation
The methyl ester is readily hydrolysed, reduced or converted to amides and other carbonyl derivatives, providing a convenient point of elaboration toward nicotinic acid and nicotinamide analogues.
Agrochemical and fine-chemical research
Applied as an intermediate in agrochemical discovery and general fine-chemical synthesis where a fluorinated nicotinate framework is required.
Laboratory reagent
Supplied as a research-grade reagent for use by synthetic, process-development and analytical chemists in laboratory-scale work.
