    Odor threshold

    • Odor Threshold Low: 0.08 [mmHg]. Detection odor threshold from AIHA (mean = 0.080 ppm)
    • Water odor threshold: 6.2 mg/L. Air odor threshold: 1.8 uL/L. Odor safety class: C. C = odor safety factor 1-26. Less than 50% of distracted persons perceive warning of TLV.
    • The odor of butylamine is slight at less than 1 ppm, noticeable at 2 ppm, moderately strong at 2 to 5 ppm, strong at 5 to 10 ppm, & strong & irritating at concentrations exceeding 10 ppm. ... concentrations of 10 to 25 ppm are unpleasant to intolerable for more than a few minutes.

  • Applications

    Butylamine (C4H11N, CAS 109-73-9) is a straight-chain aliphatic amine with moderate basicity and high miscibility in water and most organic solvents, widely exploited as a versatile intermediate for manufacturing pharmaceuticals (including antiviral agents, antihypertensives, antidepressants), agrochemicals such as carbamate insecticides and selective herbicides, as well as for producing rubber vulcanization accelerators, metal corrosion inhibitors, water-treatment additives, selective extractants in petroleum refining, flotation agents in mineral processing, curing agents and adhesion promoters for epoxy resins, precursors to butyl isothiocyanate, butyl isocyanate and cationic surfactants; it is also employed in the synthesis of dyes, paint additives and high-performance polymers, where the reactive amino group enables facile acylation, alkylation or condensation reactions and the resulting salts provide enhanced stability and ease of handling in numerous industrial formulations.
