Description

ChEBI: An organic sodium salt that is the disodium salt of 5-[(4-acetamido-2-sulfophenyl)diazenyl]-6-amino-4-hydroxynaphthalene-2-sulfonic acid. Used along with acid fuchsin as a constituent of the plasma staining solution in Lendrum's Picro-Mallory for fibrin.

Lissamine fast red is an organic sodium salt that is the disodium salt of 5-[(4-acetamido-2-sulfophenyl)diazenyl]-6-amino-4-hydroxynaphthalene-2-sulfonic acid. Used along with acid fuchsin as a constituent of the plasma staining solution in Lendrum's Picro-Mallory for fibrin. It has a role as a histological dye and a fluorochrome. It contains a lissamine fast red(2-).

Acid Red 37 Use and Manufacturing

Methods of Manufacturing

Using 2, 5-diaminobenzenesulfonic acid and gamma acid as raw materials, first react 2, 5-diaminobenzenesulfonic acid with acetic anhydride, then diazotize it, and couple with gamma acid to obtain the product. The product is obtained by salting out, filtering, drying and crushing.

Uses

Used for dyeing wool, silk and nylon
