Aniline alcohol is a chemical compound composed of aniline and alcohol, usually ethanol. In histology and cytology, aniline alcohol is commonly used as a solvent and intermediate medium.

Aniline alcohol solution is a mixture of aniline and ethanol, available in various concentrations. This solution is used as a solvent and plasticizer in various staining methods, especially in the staining of neurons and nerve fibers. By using aniline alcohol, dyes can better penetrate tissue structures and achieve more uniform staining.

In cytology, aniline alcohol can be used to stain chromosomes in cell nuclei. The aniline alcohol solution facilitates binding of the dye to DNA and allows clearer visualization of chromosome structure.

It is important to maintain proper concentrations and procedures when using aniline alcohol in laboratory and staining processes to achieve optimal results.
