diol
Let an agent explain diols, relay structure, nomenclature, uses and toxicity from chemistry and toxicology sources at public reference level, describe the named compounds, route suspected poisoning to poison centres, and distinguish diols from alcohols with one hydroxyl group, triols such as glycerol, polyols generally and diones.
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 explain diols, relay structure, nomenclature, uses and toxicity from chemistry and toxicology sources at public reference level, describe the named compounds, route suspected poisoning to poison centres, and distinguish diols from alcohols with one hydroxyl group, triols such as glycerol, polyols generally and diones.
An organic compound containing two hydroxyl groups, also called a glycol, including simple alkanediols such as ethylene glycol and propylene glycol, 1,4-cyclohexanedimethanol used in polyesters such as PETG in its cis and trans isomers, 2,3-octanediol and natural products such as cicutoxin, a highly toxic polyacetylene diol from water hemlock; diols are used in antifreeze, polymers, solvents and cosmetics, and some are poisonous, with ethylene glycol and cicutoxin poisoning medical emergencies needing a poison centre or emergency services.
What it is for: Antifreeze, polymers, solvents and other uses.
It can be explain structure and naming; relay uses and toxicity; describe named compounds; route poisoning to poison centres.
Distinguishing features
Two OH groups
Hydrogen bonding
Industrial importance
Some highly toxic
What it looks like
Often colourless, viscous, sweet-tasting liquids or solids.
Physical character
ethylene glycol boiling point: about 197 C
ethylene glycol toxicity: poisonous if swallowed, antidotes fomepizole or ethanol in hospital note
registry parent: polyol note
How it is recognised
Compound with two hydroxyl groups
Cyclohexanedimethanol, alkanediols, cicutoxin, trans- and cis-1,4-cyclohexanedimethanol, 2,3-octanediol
Alcohols have one hydroxyl; triols such as glycerol have three; polyols have many; diones have two ketone groups
