What are the applications of Application

Guinea green B is a large organosulfur stain

Definition

ChEBI: An organic sodium salt having 3-[(ethyl{4-[(4-{ethyl[(3-sulfonatophenyl)methyl]amino}phenyl)(phenyl)methylidene]cyclohexa-2,5-dien-1-ylidene}azaniumyl)methyl]benzene-1-sulfonate. Used as a substitute for Light green SF yellowish in Masson's trichrome, alth ugh it is prone to fade. Previously used as a food dye but is now no longer approved.

Preparation

Benzaldehyde (1 Moore) and 3-(Ethyl(phenyl)amino)methyl)benzenesulfonic acid (2 Moore) condensation, will product oxidation, and then translate into sodium salt.

General Description

A dull dark green powder. Used as a dye for silk or wool and biological stains.

Air & Water Reactions

Very soluble in water. Forms a green solution, which becomes brownish-yellow by addition of HCl, and blackish-green with NaOH.

Reactivity Profile

ACID GREEN 3 neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. May generate hydrogen, a flammable gas, in combination with strong reducing agents such as hydrides.

Properties and Applications

bright green. Soluble in water for the green, soluble in ethanol for blue light green. The strong sulfuric acid for lemon yellow, diluted to green. The dye solution is to join sodium hydroxide to colorless.
