Basic Violet 1 Chemical Properties,Uses,Production
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; Newtons crystal violet-iodine technique for chromatin and nucleoli; Liebs amyloid stain.
Biological Activity
Methyl violet 2B is a cationic dye with a triphenylmethane structure. It acts as a selective dye and facilitates the differentiation of Klebsiella pneumoniae from Enterobacter aerogenes and other gram-negative organisms. Methyl violet 2B is harmful if inhaled, swallowed or absorbed through skin, contact may cause damage to skin and eyes. Hence, the dye removal is of gre at importance.
Purification Methods
Crystallise 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.]
