Lysergic acid butylamide

Lysergic acid butylamide is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lysergic acid butylamide rather than just read about it. In short: Lysergic acid butylamide, also known as N-butyllysergamide (NB-LA), is a serotonin receptor modulator of the lysergamide family related to the psychedelic drug lysergic acid diethylamide (LSD). It is the analogue of LSD in which the N,N-diethyl groups have been replaced with an N-butyl group and is also the N-butyl derivative of ergine (lysergic acid amide; LSA).

Key takeaways

Lysergic acid butylamide belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lysergic acid butylamide to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lysergic acid butylamide from memory before moving on to harder problems.

Reference excerpt

Lysergic acid butylamide, also known as N-butyllysergamide (NB-LA), is a serotonin receptor modulator of the lysergamide family related to the psychedelic drug lysergic acid diethylamide (LSD). It is the analogue of LSD in which the N,N-diethyl groups have been replaced with an N-butyl group and is also the N-butyl derivative of ergine (lysergic acid amide; LSA). The drug shows 64.9% of the antiserotonergic activity of LSD in the isolated rat uterus in vitro. However, activity in this assay does not correlate with hallucinogenic activity. In addition, unlike LSD and lysergic acid ethylamide (LAE-32), the lower homologue lysergic acid propylamide is known to be inactive as a psychedelic in humans at doses of up to 500 μg orally. Lysergic acid butylamide was first described in the scientific literature by 1957.

Worked examples

Example 1 — a first encounter with Lysergic acid butylamide

Start with the simplest possible case. Write down what Lysergic acid butylamide claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lysergic acid butylamide before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lysergic acid butylamide ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lysergic acid butylamide

In research: Lysergic acid butylamide appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lysergic acid butylamide in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lysergic acid butylamide is common in secondary-school and first-year university syllabi. It links to neighbouring topics Butyl compounds, Carboxamides, Drugs not assigned an ATC code, so understanding it makes those chapters shorter.
In everyday life: Look for Lysergic acid butylamide outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
