Properties: Orthorhombic crystals with 2C6H6 from benzene. mp 155-157° (dec) (solvent-free base). [a]D20 -183° (chloroform). Very sol in ethyl and methyl alcohol, acetone, chloroform, ethyl acetate. Slightly sol in ether. Practically insol in water, petr ether.
Melting point: mp 155-157° (dec) (solvent-free base)
Optical Rotation: [a]D20 -183° (chloroform)
Derivative Type: Phosphate
CAS Registry Number: 6424-36-8
Properties: Crystals, dec 195°.
Derivative Type: Ethanesulfonate
CAS Registry Number: 6055-56-7
Properties: Crystals, dec 207°.
Derivative Type: 8a-isomer
CAS Registry Number: 511-07-9
Additional Names: Ergocristinine
Properties: Crystallizes solvent-free, unlike ergocristine which tends to retain the solvent of crystn. Long prisms from abs alc, mp 226° (dec). [a]D20 +366° (c = 0.68 in chloroform); +471° (c = 0.35 in pyridine). uv max (methanol/methylene chloride): 313 nm (log e 3.96). Much less sol than ergocristine. Does not seem to form salts.
