2-Ethylaniline Usage And Synthesis

Chemical Properties

clear yellow to red-brownish liquid

Chemical Properties

2-Ethylaniline is a yellow liquid that turns brown on standing in air

Uses

Intermediate for pharmaceuticals, dyestuffs, pesticides, and other products.

Uses

2-?Ethylaniline is a reagent in the synthesis of bromoanthraquinones with different substituents producing novel dyes. Also used in the optimization of phoephoinositide 3-kinase inhibitor which is used in the synthesis.

Synthesis Reference(s)

The Journal of Organic Chemistry, 45, p. 4926, 1980 DOI: 10.1021/jo01312a021

General Description

A brown liquid. Insoluble in water and less dense than water. Hence floats on water. Flash point 185°F. May irritate skin, eyes and mucous membranes. Toxic by ingestion, inhalation or skin absorption.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

2-Ethylaniline neutralizes acids in exothermic reactions to form salts plus water. May react with acids to release toxic fumes of aniline and oxides of nitrogen. Reacts violently with oxidizing materials. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

Flammability and Explosibility

Notclassified

Safety Profile

: A poison. Moderately toxic by ingestion. Flammable when exposed to heat or flame; can react with oxidizing materials. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits highly toxic fumes of aniline and NOx. See also NETHYLANILINE.

Potential Exposure

This material is used in making drugs, dyes, and pesticides.

Shipping

UN2273 2-Ethylaniline, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Incompatibilities

Combustible; vapor may form explosive mixture with air above 80℃. Decomposes on contact with light or air. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, anhydrides, and chloroformates. Contact with metals may evolve flammable hydrogen gas.
