75-31-0

A clear colorless liquid with an ammonia-like odor. Flash point-35°F. Boiling point 90°F. Less dense than water Vapors heavier than air. Produces toxic oxides of nitrogen during combustion. Used as a solvent and to make other chemicals.

ISOPROPYLAMINE(75-31-0) is a colorless, alkaline liquid, very volatile, moderately toxic, highly flammable. Dangerous fire hazard when exposed to heat, flame, sparks, or strong oxidizers. When heated to decomposition ISOPROPYLAMINE(75-31-0) emits toxic fumes of oxides of nitrogen [M. K.]. A mixture of ISOPROPYLAMINE(75-31-0) and perchloryl fluoride resulted in an uncontrolled oxidation and/or explosion, [J. Org. Chem., 1980, 45, 4036]. The reaction of 1-chloro-2,3-epoxypropane and the amine and most probably other nitrogen bases, yields a violent exotherm, [Chem. & Ind., 1971, 994].

Highly flammable. Water soluble.

Highly flammable, dangerous fire risk. Strong irritant to tissue.

Inhalation causes nose and throat irritation, severe coughing, and chest pain due to irritation of air passages; can cause lung edema and loss of consciousness. Ingestion causes nausea, salivation and severe irritation of mouth and stomach. Contact with eyes causes severe irritation and possible edema of the cornea. Contact with skin causes severe irritation.

Isopropylamine (propan-2-amine, IUPAC) is a colorless, volatile liquid. It is highly flammable, with a flammable range of 2%–10.4% in air. Boiling point is 93°F (33°C), flash point is ?15°F (?26°C), and ignition temperature is 756°F (402°C).
It is miscible with water, with a specific gravity of 0.69, which is lighter than water. Vapor density is 2.04, which is heavier than air. In addition to flammability, isopropylamine is a strong irritant to tissue and has a TLV of 5 ppm in air. The four-digit UN identification number is 1221. The NFPA 704 designation for isopropylamine is health 3, flammability 4, and reactivity 0. Primary uses for isopropylamine are pharmaceuticals, dyes, insecticides, and as a dehairing agent.

Isopropylamine is a colorless, flammable liquid. Isopropylamine is miscible with water, alcohol, and ether.The odor threshold reportedly ranges from 0.21 to 0.70 ppm; the pungent, ammoniacal odor becomes irritating at 24mg/m3 (110).

Colorless liquid with a penetrating, ammonia-like odor. Experimentally determined detection and recognition odor threshold concentrations were 500 μg/m³ (210 ppb_v) and 1.7 mg/m³ (700 ppb_v), respectively (Hellman and Small, 1974). An odor threshold concentration of 25 ppb_v was reported by Nagata and Takeuchi (1990).

ChEBI: A member of the class of alkylamines that is propane carrying an amino group at position 2.

Isopropylamine can be produced from the corresponding alcohol by reacting with ammonia in the presence of a dehydrating catalyst, or from the chloride by reacting with ammonia under pressure. It is also reported that this amine can be produced from acetone and ammonia or from the acetone oxime (HSDB 1989).

High strength odor; fishy type; recommend smelling in a 0.10% solution or less.

Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Isopropylamine can be used as a dehairing agent and as a solvent. It also finds use as an intermediate in the production of insecticides, herbicides and bactericides and in the production of pharmaceuticals, dyes and rubber accelerators (HSDB 1989).

Photolytic. Low et al. (1991) reported that the photooxidation of aqueous primary amine solutions by UV light in the presence of titanium dioxide resulted in the formation of ammonium and nitrate ions.
Chemical/Physical. Releases toxic nitrogen oxides when heated to decomposition (Sax and Lewis, 1987). Forms water-soluble salts with acids.

One would expect isopropylamine to be readily absorbed from the gut and respiratory tract. Shorter chain aliphatic amines such as isopropylamine also are efficiently absorbed through the skin (Beard and Noe 1981). When administered intravenously, isopropylamine distributed rapidly into tissue compartments with tissue/plasma ratios ranging from 1.8 in the atrium to 16.7 in the renal medulla (Privitera et al 1982). During the elimination phase, a half-life of 146 min was observed in plasma. There do not appear to be any definitive metabolic studies with this compound, however through a comparison with other substrates, one might expect oxidation to acetone and ammonia through the action of monoamine oxidase (Tipton 1980).

The Initial Risk Screening Level (IRSL) for isopropylamine is 120 μg/m3 based on an 8 hr. averaging time.
