Phenazopyridine is an azo dye. [17] [18] Other azo dyes, which were previously used in textiles, printing, and plastic manufacturing, have been implicated as carcinogens that can cause bladder cancer. [19] While phenazopyridine has never been shown to cause cancer in humans, evidence from animal models suggests that it is potentially ...
Azobenzene is a photoswitchable chemical compound composed of two phenyl rings linked by a N=N double bond.It is the simplest example of an aryl azo compound.The term 'azobenzene' or simply 'azo' is often used to refer to a wide class of similar compounds.
2,2'-Azobis(2-amidinopropane) dihydrochloride (abbreviated AAPH or AMPA) is a chemical compound used to study the chemistry of the oxidation of drugs. [1]It is a free radical-generating azo compound.
Azo compounds are organic compounds bearing the functional group diazenyl (R−N=N−R′, in which R and R′ can be either aryl or alkyl groups).. IUPAC defines azo compounds as: "Derivatives of diazene (diimide), HN=NH, wherein both hydrogens are substituted by hydrocarbyl groups, e.g. PhN=NPh azobenzene or diphenyldiazene.", where Ph stands for phenyl group. [1]
As an azo initiator, radicals resulting from AIBN have multiple benefits [2] over common organic peroxides. For example, they do not have oxygenated byproducts or much yellow discoloration. Additionally, they do not cause too much grafting and therefore are often used when making adhesives, acrylic fibers, detergents, etc.
Ponceau (17th century French for "poppy-coloured") is the generic name for a family of azo dyes. Ponceau 4R is a strawberry red azo dye which can be used in a variety of food products, and is usually synthesized from aromatic hydrocarbons; it is stable to light, heat, and acid but fades in the presence of ascorbic acid.
