4-Fluoro-3-methylbenzoic acid (CAS number 403-15-6), is a meta-toluic acid with a fluoride group at the 4-position. 4-Fluoro-3-methylbenzoic acid serves as a versatile building block for the synthesis of active pharmaceutical ingredients (APIs), as its functional group can be directly used or easily converted to alternative functional groups. The carboxylic acid group of 4-fluoro-3-methylbenzoic acid enables it to be attached to molecular scaffolds. Alternatively, it can be reduced to a hydroxy/aldehyde group for other type of reactions. The methyl group can be functionalised by bromide through a benzylic bromination reaction. The resulting brominated product can then be applied in the synthesis of bicyclic heterocycles.
An analogue of imidazopyridine based on 4-fluoro-3-methylbenzoic acid exhibits a potency of 0.1 nM as an anticoccidial agent.
