| Hazard Information | Back Directory | [General Description]
A clear colorless liquid with a fishlike odor. Flash point 15°F. Less dense (6.1 lb/gal) than water. Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. | [Reactivity Profile]
ISOBUTYLAMINE(78-81-9) 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. | [Air & Water Reactions]
Highly flammable. Soluble in water. | [Hazard]
Flammable, dangerous fire risk. Strong irritant to skin and mucous membranes. | [Health Hazard]
Inhalation causes severe coughing and chest pain due to irritation of air passages; can cause lung edema. Compound is sympathomimetic and is also a cardiac depressant and convulsant; ingestion causes nausea and profuse salivation. Contact with eyes causes severe irritation and edema of the cornea. Contact with skin causes severe irritation. | [Potential Exposure]
Alert: (n-isomer): Possible risk of
forming tumors, suspected of causing genetic defects, suspected reprotoxic hazard, Primary irritant (w/o allergic
reaction), (sec-isomer): Drug. n-Butylamine is used in
pharmaceuticals; dyestuffs, rubber, chemicals, emulsifying
agents; photography, desizing agents for textiles; pesticides, and synthetic agents. sec-Butylamine is used as a
fungistate. tert-Butylamine is used as a chemical intermediate in the production of tert-Butylaminoethyl methacrylate
(a lube oil additive); as an intermediate in the production
of rubber and in rust preventatives and emulsion deterrents
in petroleum products. It is used in the manufacture of
several drugs | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Rinse out mouth and do not induce vomiting.
Medical observation is recommended for 24 to 48 hours
after breathing overexposure, as pulmonary edema may be
delayed. As first aid for pulmonary edema, a doctor or
authorized paramedic may consider administering a drug or
other inhalation therapy | [Shipping]

3—Flammable liquid, 8—Corrosive material. UN2014
Isobutylamine, Hazard Class: 3; Labels: 3—Flammable
liquid, 8—Corrosive material | [Incompatibilities]
May form explosive mixture with air.
May accumulate static electrical charges, and may causeignition of its vapors. n-Butylamine is a weak base; reacts
with strong oxidizers and acids, causing fire and explosion
hazard. Incompatible with organic anhydrides; isocyanates,
vinyl acetate; acrylates, substituted allyls; alkylene oxides;
epichlorohydrin, ketones, aldehydes, alcohols, glycols, phenols, cresols, caprolactum solution. Attacks some metals in
presence of moisture. The tert-isomer will attack some
forms of plastics | [Chemical Properties]
Butyl amines are highly flammable, colorless
liquids (n-turns yellow on standing) with ammoniacal or fishlike odors. n-isomer: | [Chemical Properties]
Clear colorless to slightly yellow liquid | [Chemical Properties]
Colorless to yellow liquid; fishy cheesy aroma. | [Chemical Properties]
Isobutylamine is a flammable liquid, miscible with water, alcohol, and
ether. | [Waste Disposal]
Use a licensed professional
waste disposal service to dispose of this material. Dissolve
or mix the material with a combustible solvent and burn in
a chemical incinerator equipped with an afterburner andscrubber. All federal, state, and local environmental regulations must be observed. | [Definition]
ChEBI: An alkylamine having isobutyl as the alkyl group. It has been isolated from Sambucus nigra (Elderberry). | [Production Methods]
Isobutylamine is manufactured from isobutanol and ammonia
or by the thermal decomposition of valine to isoleucine. | [Aroma threshold values]
High strength odor, fishy type; recommend smelling in a 0.10% solution or less. | [Chemical Reactivity]
Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent. |
