补充资料:4-(甲氨基)苯酚硫酸盐
分子式:C14H18N2O2·H2SO4
分子量:344.38
CAS号:55-55-0

性质:无色针状结晶体。熔点259-260℃。溶于20份冷水、6份沸水,微溶于醇,不溶于醚。在空气中变色。

制备方法:对氨基苯酚经甲基化或对苯二酚与甲胺反应可制得以甲氨基苯酚([150-75-4]),再经成盐而得。

用途:该品是具有代表性的主要的快速显影剂,也常译音为密妥耳。单用或与对苯二酚并用均可,效果都很好,该品的相对还原能力约为对苯二酚的20倍。该品与对苯二酚按1:2-4配比制成的显影液称为MQ显影液;如与偏酸配制,则可用作微粒显影液(胶片敏感度为1/2)。
