Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent handle phenols by structure, examples, properties, uses, regulation and hazards, and route exposure to emergency help.

A class of organic compounds with one or more hydroxyl groups bonded directly to an aromatic ring, including phenol itself, cresols, catechols, bisphenols and natural polyphenols such as flavonoids and lignans.

What it is for: Chemistry, plastics, pharmaceuticals, food science and disinfectants.

It can be recognise phenol structures; find identifiers and safety data; understand regulation of bisphenols; describe natural polyphenols with sourced evidence.

Distinguishing features

Aromatic hydroxyl compounds

Weakly acidic

Include toxic and natural members

Widely used industrially

What it looks like

Phenol is a colourless to pink crystalline solid with a sweet tarry smell; others vary.

How it is recognised

OH group on an aromatic ring

Phenol, cresols, bisphenol A

Alcohols have OH on non-aromatic carbon

Structure What they are.

Structure defines the class.

Class

Membership.

Class

Class membership.

  1. Does the compound have a hydroxyl group directly on an aromatic ring? boundary
  2. How many hydroxyl groups does it have? measurement

Identifiers

  2. Which database records it? provenance
Safety Hazards.

Some phenols are dangerous.

Exposure

Emergency.

Exposure

What the second pass must settle

  • Should each phenol be a separate entry?
  • How should bisphenol rules be tracked?
  • How should food evidence be linked?
