Cyclopentylamine Chemical Properties,Uses,Production

Chemical Properties

a colorless liquid with an ammoniacal odor.

Uses

Cyclopentylamine acts as an important raw material and intermediate used in organic synthesis and pharmaceuticals. Further, it serves as chemokine receptor 2 antagonists. It acts as a ligand in coordination chemistry and forms cis-dichlorobis(cyclopentylamine)platinum(II) complex.

Preparation

Cyclopentylamine is produced from cyclopentanone and ammonia over nickel catalysts at 20 MPa and 150 – 200℃ in the presence of circulating hydrogen over a fixedbed catalyst.

Application

Cyclopentylamine is used in small amounts as an intermediate for the potato and rice fungizide pencycuron (Bayer, Nihon Tokushu, Noyaku Seizo).

Flammability and Explosibility

Highly flammable

Purification Methods

The amine may contain H2O or CO2 in the form of carbamate salt. Dry it over KOH pellets and then distil it from a few pellets of KOH. Store it in a dark, dry CO2-free atmosphere. It is characterised as the thiocyanate salt m 94.5o. The benzenesulfonyl derivative has m 68.5-69.5o. [Roberts & Chambers J Am Chem Soc 73 5030 1951, Bollinger et al.
