WebAug 24, 2016 · The triphenylmethyl (trityl) groups including the 4-monomethoxy- and 4,4′-dimethoxytrityl groups have been widely used for protecting alcohols in organic synthesis including synthesis of DNA, RNA, and peptides. These protecting groups are stable under basic conditions, and can be readily removed with a mild acid. Triphenylmethane, or triphenyl methane, is the hydrocarbon with the formula (C6H5)3CH. This colorless solid is soluble in nonpolar organic solvents and not in water. Triphenylmethane is the basic skeleton of many synthetic dyes called triarylmethane dyes, many of them are pH indicators, and some display fluorescence. A trityl group in organic chemistry is a triphenylmethyl group Ph…
