Basic Violet 1 Usage And Synthesis
SynthesisBasic 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 Propertiesgreen crystalline powder with metal lustre
UsesMethyl 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.
UsesMedicine (topical antibacterial and antialler-gen), acid–base indicator, alcohol denaturant, bio-logical stain, textile dye.
Purification MethodsCrystallise the dye from EtOH by precipitation with Et2O during cooling in an ice-bath. Filter it off and dry it at 105o. [Beilstein 13 IV 2283.]
