2-Butynoic acid is often used as an intermediate in organic synthesis. As I mentioned earlier, it can be used as a starting material in the synthesis of various pharmaceuticals, agrochemicals, and specialty chemicals.

For example, 2-Butynoic acid can be used in the synthesis of alkylidene malonates, which are key intermediates in the synthesis of various biologically active compounds. The reaction of 2-Butynoic acid with malonic acid diethyl ester yields the corresponding alkylidene malonate, which can then be used in further reactions.
