Description and Uses
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 used as a dehairing agentand as an intermediate in the preparation ofmany organics.
