Text Abstract (this page) Full Text - English (private) Show Articles by Neville GA Beckstead HD Black B Dawson BA Ethier JC Article IDs Erowid RefID: 9011 PubMedID: unknown Collections Hofmann Collection MDMA Collection All References	Abstract In subjecting a commercial supply of lysergide (LSD) tartrate (Sandoz Lot 79001) to authentication for adoption as a "working standard", infrared (IR) proton nuclear magnetic resonance (1H-NMR) spectra of the working standard showed some dissimilar features to those obtained from the USP LSD Tartrate Authentic Substance (Lot I). Although comparable mas spectral results were obtained from the two LSD samples, further investigation by 1-H- and 13C-NMR spectroscopy showed the USP material to contain appreciable excess tartaric acid.
