peroxide
Let an agent explain peroxides, relay structure, classes, uses, biological roles and hazards from chemistry and safety sources, describe the named forms, route exposure and fire emergencies, and distinguish peroxides from oxides, superoxides, ozonides and peroxidases, without synthesis instructions for hazardous compounds.
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 peroxides, relay structure, classes, uses, biological roles and hazards from chemistry and safety sources, describe the named forms, route exposure and fire emergencies, and distinguish peroxides from oxides, superoxides, ozonides and peroxidases, without synthesis instructions for hazardous compounds.
A compound containing an oxygen-oxygen single bond or the peroxide ion O2 with a 2- charge, including hydrogen peroxide, metal peroxides such as sodium and barium peroxide, and organic peroxides, with related forms the registry aliases name such as peroxy acids, hydroperoxides, alkenyl peroxides, peroxynitrous acid, a reactive species formed in biology, and chlorine peroxide, an intermediate in stratospheric ozone destruction; peroxides are used for bleaching, disinfection, polymerisation initiators and rocket propellants, and their weak O-O bond makes many of them strong oxidisers that can be unstable, so they are regulated as hazardous materials, with some organic peroxides able to explode. The model gives no instructions for making dangerous peroxides.
What it is for: Oxidising, bleaching, disinfecting and initiating reactions.
It can be explain structure and classes; relay uses; describe named forms; relay hazards and route emergencies.
Distinguishing features
Weak O-O bond
Oxidising power
Instability risks
Radical initiators
What it looks like
Varies; hydrogen peroxide is a colourless liquid, metal peroxides are pale solids.
Physical character
O-O bond energy: roughly 140-210 kJ/mol - varies by compound
household hydrogen peroxide: about 3 percent - typical
UN transport class: 5.2 organic peroxides class
How it is recognised
Compound with an O-O single bond
Peroxy acid, peroxide ion, inorganic hydroperoxide, peroxynitrous acid, alkenyl peroxide, chlorine peroxide
Oxides have O2- ions; superoxides have O2- radicals; ozonides have O3 units; peroxidases are enzymes
