Source-derived summary

OML-632, also known as 1-hydroxymethyllysergic acid diethylamide (1-hydroxymethyl-LSD), is a psychedelic drug of the lysergamide family related to lysergic acid diethylamide (LSD).

Interactions

Pharmacology

Pharmacodynamics

OML-632 has about 66% of the hallucinogenic potency of LSD in humans (which is stated as active at 50–100 μg) and about 59% of the antiserotonergic activity of LSD in the isolated rat uterus in vitro. However, OML-632 may simply act as a prodrug of LSD. It has also been said to serve as a metabolic intermediate in the demethylation of 1-methyl-LSD (MLD-41) into LSD.

History

OML-632 was first described in the scientific literature by 1957. The compound has been mistakenly referred to as "1-methoxy-LSD" or "1-MeO-LSD" in some publications.

Editorial analysis

Why this record matters

“OML-632” is worth following because a concise public description often conceals a longer documentary argument. Here, OML-632, pharmaceutical and compound provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 8, 2026. The linked authority identifier is Q133865295. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1957.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
