Chemical compound
sec-Butylamine is an organic chemical compound (specifically, an amine) with the formula CH3CH2CH(NH2)CH3. It is a colorless liquid. sec-Butylamine is one of the four isomeric amines of butane, the others being n-butylamine, tert-butylamine, and isobutylamine. sec-Butylamine is chiral and therefore can exist in either of two enantiomeric forms.
sec-Butylamine is used in the production of some pesticides.[2]
Bromacil, a commercial herbicide, is produced from sec-butylamine.[3]
Safety
The LD50 (rat) for primary alkylamines is 100 – 1 mg/kg.[2]
