1-(4-Isobutylphenyl)ethanol Chemical Properties,Usage,Production

Uses

1-(4-Isobutylphenyl)ethanol is a photodegradation product of Ibuprofen (I140000). Shows cytotoxicity activity.

Preparation

1-(4-Isobutylphenyl)ethanol synthesis: A solution of p-isobutylacetophenone (1.20mL), methanol (3.00mL), and sodium borohydride (0.2509g) was mixed in a separatory funnel and allowed to sit for 10min. After the standing time period, a 10 % HCl solution (10.0 mL) was added to remove any unreacted sodium borohydride, and the product was extracted using petroleum ether. 1-(4-Isobutylphenyl)ethanol product (1.002g, 87.2%) was collected and dried using anhydrous sodium sulfate.
