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 dicarboxylic acids by structure, examples, properties, uses and safety data.

An organic compound containing two carboxylic acid groups, such as oxalic, malonic, succinic, glutaric, adipic and phthalic acids; many are used to make polymers such as nylon and polyesters, and some occur naturally in metabolism.

What it is for: Polymers, food additives, pharmaceuticals and biochemistry.

It can be recognise dicarboxylic acid structures; find identifiers and properties; describe industrial uses; look up safety data.

Distinguishing features

Two carboxyl groups

Two dissociation constants

Polymer building blocks

Some are toxic, such as oxalic acid

What it looks like
