General description

Cresyl violet acetate, also known as oxazine 9, is a small diaminobenzooxazine dye that has a planar conjugated system of moderate size.

Application

Cresyl Violet acetate has been used in Nissl staining of sections of the spinal cord and brain. It is also suitable for the demonstration of nuclei and Nissl substance in neuroanatomical investigations. Additional applications of Cresyl violet include staining of sex chromatin, identification of Helicobacter, and diagnostically as a vital stain in endoscopic procedures.
