LSD er LSD, som sagt lengre oppe, men om vi skal være helt teknisk så:
I kjemi så har man noe som heter
Entianomerer, LSD har 4 stk:
Disse har desverre akkurat de samme egenskapene som originalen og de blir ikke laget under produksjonen av LSD; 2 av de er teoretiske og har aldri blitt syntesert:
SD is a chiral compound with two stereocenters at the carbon atoms C-5 and C-8, so that theoretically four different optical isomers of LSD could exist. LSD, also called (+)-D-LSD,[citation needed] has the absolute configuration (5R,8R). The C-5 isomers of lysergamides do not exist in nature and are not formed during the synthesis from d-lysergic acid. Retrosynthetically, the C-5 stereocenter could be analysed as having the same configuration of the alpha carbon of the naturally occurring amino acid L-tryptophan, the precursor to all biosynthetic ergoline compounds.
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.
Pure salts of LSD are triboluminescent, emitting small flashes of white light when shaken in the dark.[67] LSD is strongly fluorescent and will glow bluish-white under UV light.
LSD er veldig ustabilt og uegnet lagring vil ødelegge stoffet slik at man ikke får noen effekt. Men i sin salt-form i vann kan det lagres mørkt, uten tilgang på luft for å i teorien kunne vare evig.
