Chemical Properties
reddish brown powder
Uses
Weakly acidic azo dye. Biological stain. Dyes and metabolites, Environmental Testing.
Preparation
4-(Phenyldiazenyl)benzenamine diazotization, and Naphthalen-2-ol coupling. Note: some goods by 4-(Phenyldiazenyl)benzenamine and 2-Methyl-4-(o-tolyldiazenyl)benzenamine mixture as diazo components and have to.
Definition
ChEBI: A bis(azo) compound that is 2-naphthol substituted at position 1 by a 4-{[(2-methylphenyl)diazenyl]phenyl}diazenyl group. A fat-soluble dye predominantly used for demonstrating triglycerides in frozen sections, but which may also stain some protein bound l pids in paraffin sections.
Contact allergens
Solvent Red 23 is an oil-soluble red azo-dye used in cosmetic products in Japan. Cases were reported in hairdressers, who also reacted to PPD (the molecule is likely to be hydrolyzed into PPD) and to p-aminoazobenzene. One case of contact dermatitis was reported in the metal industry.
Safety Profile
Poison by intraperitoneal route. Moderately toxic by subcutaneous and intrapleural routes. Questionable carcinogen. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.
Purification Methods
Crystallise the dye from EtOH, EtOH/water or *benzene/absolute EtOH (1:1). [Beilstein 16 II 75, 16 III 148, 16 IV 248.]
Properties and Applications
yellow red to red. Soluble in ethanol and acetone, soluble in benzene. In concentrated sulfuric acid to blue light green, dilution for blue solution, and a red precipitation.
