Meaning and Definition

Any of several isomeric organic compounds consisting of a phenol group with an amino group attached to the benzene ring.

A class of chemical compounds used as intermediates in the synthesis of pharmaceuticals (notably paracetamol/acetaminophen), dyes, and other industrial chemicals.

Dialectal Variation

British vs American Usage

Differences

No significant lexical differences. Spelling is identical. Pronunciation differences follow general BrE/AmE patterns for the component parts (amino-, phenol).

Connotations

Neutral, purely technical term in both varieties.

Frequency

Extremely low frequency in general language, appearing almost solely in chemical and pharmaceutical contexts. Frequency is identical across varieties within those domains.

Common Mistakes When Using “aminophenol”

  • Misspelling as 'aminophenal' or 'aminophenole'.
  • Using it to refer to the final drug (paracetamol) rather than its precursor.
  • Incorrect stress: stressing 'phenol' on the first syllable instead of the last.

FAQ

Frequently Asked Questions

No. Aminophenol (specifically para-aminophenol) is a key chemical precursor used in the synthesis of paracetamol (acetaminophen), which is the final active drug.

No. It is an industrial and laboratory chemical, not a consumer medication. The consumer product is the finished drug like paracetamol.

The amino group (-NH2) can attach at different positions on the benzene ring relative to the hydroxyl group (-OH), creating isomers (ortho, meta, para) with different chemical properties.

Like many industrial chemicals, it can be toxic and require safe handling procedures. It is not for casual or unqualified use.
