用途有機合成原料。
使用4,4'-Dimethoxytrityl chloride is used as a protective reagent for oligonucleotide synthesis. It is used for selective protection and deprotection procedures for thiol and hydroxy groups in nucleoside derivatives.
純化方法DMT crystallises from cyclohexane/acetyl chloride as the hydrochloride. Dry it over KOH pellets in a desiccator. When dissolved in *C6H6 and air is blown through, HCl is removed. It crystallises from Et2O. [Baeyer & Villiger Chem Ber 36 2788 1903, Smith et al. J Am Chem Soc 84 430 1962, Smith et al. J Am Chem Soc 85 3821 1963.] Ifit has hydrolysed considerably (see OH in IR), then repeat the crystallisation from cyclohexane/acetyl chloride — excess of AcCl is removed in a vacuum over KOH, then recrystallise it from Et2O. [Beilstein 6 IV 1042.]
