| | Cyclopentylamine Usage And Synthesis |
| 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. J Am Chem Soc 75 1729 1953, Beilstein 12 IV 4.] |
