Lysergic acid Specification

The CAS registry number of Lysergic acid is 82-58-6. Its EINECS registry number is 201-431-9. The systematic name is (8β)-6-methyl-9,10-didehydroergoline-8-carboxylic acid. In addition, the molecular formula is C16H16N2O2 and the molecular weight is 268.31. It is also called Ergoline-8-carboxylicacid,9,10-didehydro-6-methyl-,(8b)-. What's more, it is a precursor for a wide range of ergoline alkaloids that are produced by the ergot fungus and some plants. It is usually produced by hydrolysis of lysergamides, but can also be synthesized in the laboratory by a complex total synthesis.
