CAS 943-27-1

4′-tert-Butylacetophenone

Description:

4′-tert-Butylacetophenone, with the CAS number 943-27-1, is an organic compound belonging to the class of ketones. It features a tert-butyl group attached to the para position of an acetophenone structure, which consists of a phenyl ring bonded to an acetyl group. This compound is typically a colorless to pale yellow liquid with a characteristic sweet, floral odor. It is known for its applications in the fragrance industry and as a potential intermediate in organic synthesis. The presence of the bulky tert-butyl group contributes to its steric hindrance, influencing its reactivity and physical properties. 4′-tert-Butylacetophenone is relatively stable under standard conditions but should be handled with care due to potential irritant properties. It is soluble in organic solvents but has limited solubility in water. As with many organic compounds, proper safety measures should be taken when handling this substance, including the use of personal protective equipment and working in a well-ventilated area.

4-tert-Butylacetophenone

CAS: 943-27-1

4-tert-Butylacetophenone is an organic compound that is used to synthesize a variety of derivatives. It has been shown to have anticancer activity in vitro and in vivo, as well as antiviral activity against human pathogens. 4-tert-Butylacetophenone has also been shown to be active against Trichophyton mentagrophytes, a fungus that causes athlete's foot, and Cryptococcus neoformans, which is a pathogenic yeast that causes cryptococcal meningitis. The synthesis of 4-tert-butylacetophenone begins with the reaction of phosphorus pentoxide with a molecule of acetic acid in the presence of water. This reaction produces water and trichloroacetic acid as byproducts. The chloride ion then reacts with the trichloroacetic acid to form 4-tert-butylchloroacetic acid, which can then be reacted with phosphorous pentoxide again to
