4-Ethynylpyridine is an organic compound characterized by the presence of a pyridine ring substituted with an ethynyl group at the 4-position. Its molecular formula is C8H7N, and it features a triple bond between the carbon atoms of the ethynyl group, contributing to its reactivity. This compound is typically a colorless to pale yellow liquid with a distinct odor. It is soluble in organic solvents such as ethanol and ether but has limited solubility in water. 4-Ethynylpyridine is known for its role as a building block in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals. Additionally, it can participate in reactions such as nucleophilic substitutions and coupling reactions due to the presence of the ethynyl group. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested. Proper storage in a cool, dry place away from incompatible substances is recommended to maintain its stability.
