Brown powder. Soluble in water to a yellowish-brown color, slightly soluble in ethanol and ethylene glycol ether, insoluble in acetone, benzene, and carbon tetrachloride. The dye is brown in concentrated sulfuric acid, turning reddish-brown upon dilution. In concentrated nitric acid, it forms an orange solution that turns yellow. Addition of hydrochloric acid to its aqueous solution does not change the color, but addition of 10% sodium hydroxide produces an orange precipitate. | [Definition]
ChEBI: Basic brown 1 is a bis(azo) compound that is 1,1'-(1,3-phenylene)bis(diazene) in which both azene hydrogens are replaced by 2,4-diaminophenyl groups. A metachromatic dye which stains acid mucins yellow. It is also a constituent of Papanicolaou's EA solutions, used for cervical, and other smears. Its dihydrochloride salt is also a biological dye known as Bismark brown Y. It has a role as a fluorochrome and a histological dye. It is a bis(azo) compound, a member of azobenzenes, a tetramine and a substituted aniline. |
