使用
Triphenylmethane is a triarylmethane compound used as the backbone of synthetic dyes. Triphenylmethane has also been shown to inhibit 3-methylcholanthrene-induced neoplastic transformation of 10T1/2 cells.
定義
ChEBI: A triarylmethane in which the three aryl groups are phenyl. It forms the basic skeleton of several synthetic dyes.
純化方法
Crystallise triphenylmethane from EtOH or *benzene (with one molecule of *benzene of crystallisation which is lost on exposure to air or by heating on a water bath). It can also be sublimed under vacuum. It has been given a preliminary purification by refluxing with tin and glacial acetic acid, then filtered hot through a glass sinter disc, and precipitated by addition of cold water.
