1‐Propionyl‐ d ‐lysergic acid diethylamide hemitartrate (1P‐LSD) has become available as a ‘research chemical’ in the form of blotters and powdered material. This non‐controlled derivative of d ‐lysergic acid diethylamide (LSD) has previously not been described in the published literature despite being closely related to 1‐acetyl‐LSD (ALD‐52), which was developed in the 1950s. This study...
The structurally diverse nature of the 1,2-diphenylethylamine template provides access to a range of substances for drug discovery work but some have attracted attention as 'research chemicals'. The most recent examples include diphenidine, i.e. 1-(1,2-diphenylethyl)piperidine and 2-methoxydiphenidine, i.e. 1-[1-(2-methoxyphenyl)-2-phenylethyl]piperidine (MXP, methoxyphenidine, 2-MXP) that have...
