However, LSD and iso-LSD, the two C-8 isomers, rapidly interconvert in the presence of bases, as the alpha proton is acidic and can be deprotonated and reprotonated. Non-psychoactive iso-LSD which has formed during the synthesis can be separated by chromatography and can be isomerized to LSD.
A totally pure salt of LSD will emit small flashes of white light when shaken in the dark. LSD is strongly fluorescent and will glow bluish-white under UV light.
"LSD," writes the chemist Alexander Shulgin, "is an unusually fragile molecule." It is stable for indefinite time if stored as a solid salt or dissolved in water, at low temperature and protected from air and light exposure.
