Pyridine, 2,5-diethynyl- (CAS 137000-75-0) is a heterocyclic organic compound characterized by a six-membered aromatic ring containing one nitrogen atom. This compound features two ethynyl groups (-C≡CH) attached to the 2 and 5 positions of the pyridine ring, which significantly influences its chemical reactivity and physical properties. The presence of the ethynyl groups enhances its potential for further chemical modifications, making it a valuable intermediate in organic synthesis and materials science. Pyridine derivatives are known for their applications in pharmaceuticals, agrochemicals, and as ligands in coordination chemistry. The compound is typically a colorless to pale yellow liquid or solid, depending on its state at room temperature, and exhibits a characteristic aromatic odor. Its solubility in organic solvents and limited solubility in water is typical for pyridine derivatives. Safety precautions should be observed when handling this compound, as it may pose health risks, including irritation to the skin and respiratory system.
