Basic Violet 1 Usage And Synthesis
Synthesis
Basic Violet 1 can be synthesized by oxidative condensation of dimethylaniline under the action of copper sulfate, phenol and salt, and then through basic transformation, acid transformation and salting out.
Chemical Properties
green crystalline powder with metal lustre
Uses
Medicine (topical antibacterial and antialler-gen), acid–base indicator, alcohol denaturant, bio-logical stain, textile dye.
Uses
Methyl violet 2B is a biological stain that is commonly used at a pH between 0 and 1.6. It is certified for use in Flemming triple stain with iodine for chromosomes; Newton?s crystal violet-iodine technique for chromatin and nucleoli; Lieb?s amyloid stain.
