| | ALPHA-ERGOCRYPTINE Usage And Synthesis |
| Chemical Properties | Pale Yellow Solid | | Uses | An impurity of 2-Bromo α-Ergocriptine Mesylate (B682600). | | Uses | α-Ergocryptine is an ergopeptine and one of the ergot alkaloids. An impurity of 2-Bromo α-Ergocryptine Mesylate (B682600). | | Definition | ChEBI: Ergotaman bearing hydroxy, isopropyl, and 2-methylpropyl groups at the 12', 2' and 5' positions, respectively, and oxo groups at positions 3', 6', and 18. It is a natural ergot alkaloid. Ergocryptine discussed in the literature prior to 1967, when b
ta-ergocryptine was separated from alpha-ergocryptine, is now referred to as alpha-ergocryptine. | | Purification Methods | It crystallises with solvent of crystallisation, from acetone, *benzene or methanol. [Stadler et al. Helv Chim Acta 52 1549 1969, Beilstein 25 III/IV 964, 27 II 860.] |
