The Uses of 2,2'-((4-((2-Hydroxyethyl)amino)-3-nitrophenyl)imino)bisethanol

2,2′-[4-(2-Hydroxyethylamino)-3-nitrophenylimino]diethanol may be employed to improve the visibility of self-healing ureidopyrimidinone (UPy) hydrogel (poly(ethylene glycol) containing bifunctional UDP groups).

Definition

ChEBI: HC Blue No. 2 is a C-nitro compound.

General Description

Dark blue to dark brown microcrystalline powder.

Air & Water Reactions

May be sensitive to prolonged exposure to air. Slow oxidation. Insoluble in water.

Reactivity Profile

A nitrated aromatic, amine and alcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
