What is 4'-Aminoacetanilide?

Chemical properties

PINK TO BROWN FINE CRYSTALLINE POWDER

The Uses of 4'-Aminoacetanilide

Intermediate in the manufacture of azo dyes, pharmaceuticals.

General Description

White or slightly reddish solid.

Air & Water Reactions

Slightly soluble in water.

Reactivity Profile

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.

Hazard

Moderate toxicity by ingestion.

Fire Hazard

Flash point data are not available for 4'-Aminoacetanilide, but 4'-Aminoacetanilide is probably combustible.

Purification Methods

Crystallise the anilide from water. It has an unstable crystalline form with m 141o. It has IR: max (CCl4) 1681cm-1. [Beilstein 13 H 94, 13 I 28, 13 II 50, 13 III 166, 13 IV 137.]
