azo dye

a type of nitrogen-containing compound used in commercial coloring materials. Some forms of the chemical are potential carcinogens.

azo dye

A group of dyes produced from amino compounds by diazotisation and coupling of the reactants; the reactions are a function of the number groups in the molecule.
 
Uses
Plastics, rubber and in the cattle industry; the carcinogenicity of these substances is related to the ortho-hydroxylated metabolites complexed with sulphates and glucuronic acid.

azo dye

any of a class of artificial dyes obtained from aromatic amines.

dye

any of various colored substances containing auxochromes and thus capable of coloring substances to which they are applied; used for staining and coloring, as test reagents, and as therapeutic agents.

acridine dye
acriflavine and proflavine are antiseptic dyes.
azo dye
dyes like scarlet red and phenazopyridine are used as antiseptics to be applied topically or as urinary antiseptics.
diagnostic dye
several diagnostic test procedures involve the administration of a dye and determination of the rate of excretion, either by measuring levels remaining in the body or amounts excreted in the urine, feces, etc. Examples are the bromsulfthalein (BSP) test for liver function, and the phenolsulfonphthalein (PSP) renal function test.
dye dilution method
the standard method of measuring circulating plasma volume; based on the degree of dilution of a physiologically inert dye injected intravenously.
vital dye
see vital stain.
