In pure compounds, reactivity is regulated by the physical properties of the sample.

Previously, no one had successfully isolated pure compounds from these oils.

The pure compound is white, but typical samples are coloured.

Typically a small amount (5-100 mg) of pure compound is used, and crystals are allowed to grow very slowly.

Dithionous acid has not been detected either as a pure compound or in solution.

The pure compound is stable up to 96 C, when it polymerizes.

In the preceding section, boiling points of pure compounds were covered.

Most (but not all) plastics, on the other hand, are pure compounds.

It takes two to three days to produce 30 to 100 grams of pure compound.

The mixture will evaporate at different times, and is then caught in a container as a pure compound.
