Definition

ChEBI: (S)-hydratropic acid is a hydratropic acid. It is an enantiomer of a (R)-hydratropic acid.

Purification Methods

Purify the acids by vacuum distillation and by recrystallisation from pet ether. The S-anilide has m 103-104o (from H2O or CHCl3/*C6H6), [] D +47o (c 9, Me3CO) [Argus & Kenyon J Chem Soc 916 1939, Campbell & Kenyon J Chem Soc 25 1946, Levene et al. J Biol Chem 88 27, 34 1930].
