Entity of the month
Valproic acid (CHEBI:39867, also known as VPA, dipropylacetic acid, DPA, 2-propylvaleric acid, or 2-propylpentanoic acid) was first synthesised as an analogue of the valerian metabolite valeric acid (pentanoic acid) in 1881 . A high-boiling (220 °C), colourless liquid that is very soluble in organic solvents but almost insoluble in water, it became widely used as a solvent for organic chemicals. However, its remarkable anticonvulsant (antiepileptic) properties only came to light by chance some 80 years after it was first synthesised.
