1-(2,5-Dimethylphenyl)ethanone

Description:

1-(2,5-Dimethylphenyl)ethanone, also known as 2,5-Dimethylacetophenone, is an organic compound characterized by its ketone functional group. It features a phenyl ring substituted with two methyl groups at the 2 and 5 positions, along with an ethanone moiety. This compound typically appears as a colorless to pale yellow liquid with a distinctive aromatic odor. It is moderately soluble in organic solvents such as ethanol and ether but has limited solubility in water due to its hydrophobic nature. The compound is primarily used in the synthesis of various organic compounds and as a flavoring agent in the food industry. Its chemical structure allows it to participate in various reactions, including Friedel-Crafts acylation and other electrophilic aromatic substitutions. Safety data indicates that it should be handled with care, as it may cause irritation to the skin and eyes. Proper storage in a cool, dry place away from light is recommended to maintain its stability and prevent degradation.

2',5'-Dimethylacetophenone

CAS: 2142-73-6

2,5-Dimethylacetophenone is an alcohol with a chiral center. It is synthesized by reacting chlorinating agents with the ligand periconia, which leads to high yield and regiospecificity. The reaction system can be carried out in solvents such as diethyl ether or dichloromethane. The product is obtained as a mixture of two stereoisomers (R and S) with the R form being more abundant than the S form due to steric effects.
2,5-Dimethylacetophenone has been shown to react with naphthylamine in the presence of a base to give N-(2,5-dimethylphenyl)naphthalene-1,4-diamine in good yield.
