PATENT BLUE V Usage And Synthesis
Usesdouble labeled product for electron microscopy and fluorescence research
UsesPatent Blue V (CAS# 3536-49-0) is a water-soluble food colouring. Patent Blue V has also been used as a standard for high-performance liquid chromatography-diode array detection for dating of paper ink. Dyes and metabolites, Environmental Testing
Preparation(a) 3-Nitrobenzaldehyde?and N,N-diethylbenzenamine (2 Moore) condensation, then reduction, then the amino diazotization and then translate into hydroxyl compound, and then two stlfonation, finally will product into calcium salt, and segregation and oxidation; (b)3-Hydroxybenzaldehyde and N,N-diethylbenzenamine (2 Moore) condensation, and then two stlfonation, into calcium salt and oxidation. The dyes can also be as sodium salting out.
DefinitionChEBI: C.I. Acid Blue 3 is a diarylmethane.
Flammability and ExplosibilityNotclassified
Properties and Applicationscolourful green light blue. Soluble in cold water and hot water for the blue, soluble in ethanol for green light blue. The strong sulfuric acid for olive tan. In water solution to join sodium hydroxide low temperature discoloration, heat into deep purple.
