Substituted naphthylethylamine

Substituted naphthylethylamine 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 Substituted naphthylethylamine rather than just read about it. In short: The substituted naphthylethylamines are a class of chemical compounds based on naphthalene. Many naphthylethylamines are naphthylaminopropanes (also known as naphthylisopropylamines) due to the presence of a methyl group at the alpha carbon of the alkyl chain.

Key takeaways

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

Reference excerpt

The substituted naphthylethylamines are a class of chemical compounds based on naphthalene. Many naphthylethylamines are naphthylaminopropanes (also known as naphthylisopropylamines) due to the presence of a methyl group at the alpha carbon of the alkyl chain. The naphthylethylamines are derivatives of the phenethylamines, while the naphthylaminopropanes are derivatives of the amphetamines. There are two types of naphthylethylamines based on positional isomerism: 1-naphthylethylamines and 2-naphthylethylamines. Examples of these include 1-naphthylaminopropane (1-NAP) and 2-naphthylaminopropane (2-NAP), respectively.

List of substituted naphthylethylamines The substituted napthylethylamines include the following compounds:

Additional naphthylethylamines include 4-NEMD, centanafadine (EB-1020), nafimidone, naphazoline, and xaliproden (SR-57746). Some synthetic cannabinoids such as THJ-018 and THJ-2201 are also naphthylethylamines.

Related compounds Some related compounds that are not technically naphthylethylamines include 1-naphthylpiperazine and its derivatives like CSP-2503, F-11,461, S-14506, and S-14671. Another related compound is 2-naphthylpiperazine. DMNPC is a 2-naphthylpiperidine.

Pharmacology Many naphthylethylamines, like 2-naphthylaminopropane and derivatives, act as monoamine releasing agents (MRAs), monoamine reuptake inhibitors (MRIs), and/or monoamine receptor modulators. Naphthylpropylaminopentane (NPAP) is a monoaminergic activity enhancer (MAE). Some, such as 2-naphthylaminopropane and to a lesser extent 1-naphthylaminopropane, but not others, such as NPAP, are also variably potent monoamine oxidase inhibitors (MAOIs).

Worked examples

Example 1 — a first encounter with Substituted naphthylethylamine

Start with the simplest possible case. Write down what Substituted naphthylethylamine 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 Substituted naphthylethylamine 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 Substituted naphthylethylamine 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 Substituted naphthylethylamine

In research: Substituted naphthylethylamine 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 Substituted naphthylethylamine 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: Substituted naphthylethylamine is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1-Naphthyl compounds, 2-Naphthyl compounds, Chemical classes of psychoactive drugs, so understanding it makes those chapters shorter.
In everyday life: Look for Substituted naphthylethylamine 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.
