Verwenden3-Ethynylpyridine is a monoethynylpyridine isomer characterized by a DFT-calculated total energy of -324.442796 hartree, a relative energy of 0.00 kcal/mol, and a dipole moment of 2.03 Debye[1]. It serves as a starting material to yield dihydropyridine carboxylic acid derivative in low yield under triflic anhydride and ketene acetal reaction protocols[2].
