| | 2,2,6,6-Tetramethyl-4-piperidinol Usage And Synthesis |
| Chemical Properties | white to slightly beige crystalline powder | | Uses | 2,2,6,6-tetramethyl-4-piperidinol has been used to study the irradiation of Camptothecin (CPT) in aerated dimethylsulfoxide (DMSO) solution that leads to formation of singlet oxygen. | | Uses | An intermediate in the preparation of Piperidinyloxy free radical derivatives. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 37, p. 2050, 1972 DOI: 10.1021/jo00977a047 | | Purification Methods | The piperidine crystallises from water as a hydrate and crystallises from dry ether or *C6H6 as the anhydrous base. The hydrochloride has m 282-284o (from EtOH/H2O), and the formate has m 207o(dec, from EtOH/EtOAc). [Mailey & Day J Org Chem 22 1061 1957, Beilstein 21 I 195, 21 III/IV 146, 21/1 V 159.] |
