用途
用途
有機合成原料。
説明
2-(4-Methylphenyl)ethanol, also known as 4-Methylphenethyl alcohol, 2-(p-Tolyl)ethanol, is an oily liquid that can promote bile secretion and protect the liver. It is capable of transporting fat from the liver to the extrahepatic fat pool via the bloodstream and has demonstrated a significant inhibitory effect on liver cell destruction caused by alcoholism.
使用
4-Methylphenethyl alcohol was used in the determination of adducts of 1,2- and 1,4-benzoquinone with cysteine residues of hemoglobin and albumin.
製法・合成法
製造方法
To prepare 2-(4-Methylphenyl)ethanol, start with 4'-Methylacetophenone as the raw material. Reduce it to 4-methyl-α-phenylethanol using sodium borohydride in ethanol. Mix nicotinic acid with phosphorus oxychloride in pyridine to create nicotinyl chloride. Without separation, add the nicotinyl chloride to the 4-methyl-α-phenylethanol and esterify it into 2-(4-Methylphenyl)ethanol.
