What is TRIISOBUTYLAMINE?

Chemical properties

Triisobutylamine is flammable.

The Uses of TRIISOBUTYLAMINE

Triisobutylamine is suitable to develop second generation ionic liquid matrices for MALDI-MS of peptides, proteins and carbohydrates. It may be used in the separation of cis-fatty acid salts and and trans-fatty acid (elaidic acid) salts using a new organic solvent nanofiltration membrane based on polydicyclopentadiene. It may be used as base in the synthesis of acroyl ammonium derivatives.

What are the applications of Application

Triisobutylamine is suitable to develop second generation ionic liquid matrices for MALDI-MS of peptides, proteins and carbohydrates

Production Methods

Triisobutylamine is manufactured from isobutanol and ammonia under heat and pressure.

General Description

Clear pale yellow liquid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

TRIISOBUTYLAMINE 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. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Health Hazard

ACUTE/CHRONIC HAZARDS: Toxic.

Fire Hazard

TRIISOBUTYLAMINE is combustible.
