Phenyl acetyl carbinol
WebTriphenylmethanol (also known as triphenylcarbinol and TrOH) is an organic compound. It is a white crystalline solid that is insoluble in water and petroleum ether, but well soluble in ethanol, diethyl ether, and benzene. In strongly acidic solutions, it produces an intensely yellow color, due to the formation of a stable "trityl" carbocation. WebL-Phenyl Acetyl Carbinol (L-PAC) is the starting material for the chemical synthesis of L-Ephidrine hydrochloride and D-pseudoephedrine two pharmaceutical compounds used as a decongestant, anti-asthamatics and reports have indicated also its potential use in obesity control (Shin and Rogers, 1995). ...
