AZOCARMINE B - Introduction
hydrogen 5-[(2,4-diulphonatophenyl) amino]-7-phenylsulphonatobenzo[a]phenazinium, disodium salt, also known as hydrogen 5-[(2,4-diulphonatophenyl) amino]-7-phenylsulphonatobenzo[a]phenazinium, diodium salt hydrochloride, is a red organic synthetic dye. Its chemical name is 5-[(2,4-disulfonic acid phenyl) amino]-7-phenylsulfonic acid benzopyrrole, disodium salt of zinc hydroxide.
hydrogen 5-[(2,4-diulphonatophenyl) amino]-7-phenylsulphonatobenzo[a]phenazinium, diodium salt has strong coloring property and is widely used in textile, leather, plastic, coatings and other industries, used as dyes, pigments, marking agents. It also has applications in dye-sensitized solar cells.
hydrogen 5-[(2,4-diulphonatophenyl) amino]-7-phenylsulphonatobenzo[a]phenazinium, diodium salt can be synthesized from benzopyrrolidone through coupling reaction. First, two sulfonic acid groups are introduced into benzopyrrolidone, and then this compound is coupled with aniline to obtain hydrogen 5-[(2,4-diulphonatophenyl) amino]-7-phenylsulphonatobenzo[a]phenazinium, disodium salt.
Regarding safety information, hydrogen 5-[(2,4-disulphonatophenyl)amino]-7-phenylsulphonatobenzo[a]phenazinium, disodium salt is relatively safe under normal conditions of use. However, it is an organic compound and inhalation of its dusts and gases should be avoided. Long-term exposure to hydrogen 5-[(2,4-diulphonatophenyl) amino]-7-phenylsulphonatobenzo[a]phenazinium, disodium salt may be toxic, so you should follow the safe operation rules when using, avoid contact with skin and eyes. At the same time, its release in the environment should be avoided to avoid pollution to the environment. Local regulations and standards should be followed when handling this compound.
