Description:2-Ethynylpyridine is an organic compound characterized by the presence of a pyridine ring substituted with an ethynyl group at the 2-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 distinctive odor. It is soluble in organic solvents such as ethanol and ether but has limited solubility in water due to its hydrophobic nature. 2-Ethynylpyridine is known for its applications in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals. The presence of the ethynyl group enhances its utility in cross-coupling reactions and other transformations in synthetic organic chemistry. Additionally, it exhibits some biological activity, making it of interest in medicinal chemistry. As with many organic compounds, proper handling and safety precautions are essential due to its potential toxicity and flammability.
