碱性品红

溶于冷水或热水呈红紫色，极易溶于酒精呈红色；遇浓硫酸呈黄棕色，稀释后几乎无色；水溶液加氢氧化钠液呈带有红色沉淀的几乎无色的液体。 用于配制席夫试剂检测醛类，用于萃取光度法测定某些酸根离子及金属离子。也用于光度法检测溴，亚硝酸盐和二氧化硫。用作极谱分析中的极大抑制剂。还用作生化分析的核染料,为最强的核染料，能使粘朊、弹性组织及嗜品红的颗粒染色，中枢神经的核染色，细菌学中用以鉴别结核杆菌，分析化学中配制席夫试剂检验醛类。用溴酸盐滴定的氧化还原指示剂。

Basic Fuchsin is a dye composed of rosaniline, magenta II, pararosaniline, and new fuschsine. The fluorescent dye has been used for Ziehl-Neelson staining in order to detect acid-fast bacilli. The dyes fluorescence has been useful in understanding microfissures, as it allows a clear delineation of surface level structure and constant background from the microscope. Basic Fuchsin staining includes tissue sections to visualize elastic fibers, and cardiac and skeletal muscle tissue. Reports show that Basic Fuchsin has the ability to stain tubercle Bacillus, bacterial flagella, and to compare Escherichia coli and Aerobacter aerogenes.
