Succinic acid, originally called spirit of amber, is a dicarboxylic acid with the formula:

HOOC-CH2-CH2-COOH

At room temperature, pure succinic acid is a solid that forms colorless, odorless prisms. It has a melting point of 185 °C and a boiling point of 235 °C. The anion, succinate, is a component of the citric acid cycle and is capable of donating electrons to the electron transfer chain via the following reaction:

succinate + FAD → fumarate + FADH2

Esters of succinic acid are called dialkyl succinates.

History

Spirit of amber was procured from amber by pulverising and distilling it by a sand heat (a sand bath; vessel filled with heated sand). It was chiefly used externally for rheumatic aches and pains, and internally in inveterate gleets.

Safety

The acid is combustible and corrosive, capable of causing burns. "Harmful by inhalation, ingestion and through skin absorption. Wash after handling. Eye contact may cause serious damage."
