2-Ethynylpyridine

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.

2-Ethynylpyridine

CAS: 1945-84-2

2-Ethynylpyridine is a structural analog of pyridine and is used in the synthesis of polymers. 2-Ethynylpyridine has been shown to have significant cytotoxicity, which may be due to its ability to bind to receptors. Using X-ray crystallography, it has been determined that 2-ethynylpyridine binds to a receptor by forming hydrogen bonds with the nitrogen atoms on the receptor. 2-Ethynylpyridine can also be activated by hydrochloric acid (HCl) and reacts with sodium hydroxide (NaOH) solution and x-rays to form an x-ray crystal structure. 2-Ethynylpyridine is synthesized by the reaction between ethyne and nitric acid in the presence of aluminum chloride (AlCl3). The product is reacted with hydrochloric acid (HCl) or sodium hydroxide (NaOH) solution, which causes a change in
