ALPHA-ERGOCRYPTINE Usage And Synthesis

Chemical Properties

Pale Yellow Solid

Uses

α-Ergocryptine is an ergopeptine and one of the ergot alkaloids. An impurity of 2-Bromo α-Ergocryptine Mesylate (B682600).

Uses

An impurity of 2-Bromo α-Ergocriptine 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.]
