CAS 873-73-4

1-chloro-4-ethynylbenzene

Description:

1-Chloro-4-ethynylbenzene, with the CAS number 873-73-4, is an organic compound characterized by a benzene ring substituted with a chlorine atom and an ethynyl group at the para position. This compound is typically a colorless to pale yellow liquid and is known for its aromatic properties. It is insoluble in water but soluble in organic solvents, making it useful in various chemical reactions and applications. The presence of the ethynyl group introduces a triple bond, which can participate in further chemical reactions, such as polymerization or coupling reactions. The chlorine atom enhances the compound's reactivity, allowing it to undergo nucleophilic substitution reactions. 1-Chloro-4-ethynylbenzene is often utilized in the synthesis of more complex organic molecules, including pharmaceuticals and agrochemicals. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested, and appropriate protective measures should be employed to minimize exposure.

4-Chlorophenylacetylene

CAS: 873-73-4

4-Chlorophenylacetylene is a compound that is created by the reaction of chloroform and acetylene. The reaction yield can be increased by using a catalytic amount of silicon, which increases the rate of hydration. Terminal alkynes react with 4-chlorophenylacetylene to form polymers, which are insoluble in most solvents. 4-Chlorophenylacetylene has been shown to have inhibitory activity against the growth of bacteria and fungi when tested in model species such as Escherichia coli and Saccharomyces cerevisiae.
