L-2-Aminobutanamide hydrochloride (CAS No. 7682-20-4; Synonyms: Butanamide, 2-amino-,hydrochloride;L-2-Aminobutanamide Hydrochloride;Butanamide,2-amino-, monohydrochloride, (2S)-;Butanamide, 2-amino-,monohydrochloride, (S)-;Butyramide, 2-amino-, monohydrochloride, L-;(S)-2-Aminobutyramide Hydrochloride;(S)-2-Aminobutanamide Hydrochloride; IUPAC Name: (2S)-2-Aminobutanamide Hydrochloride) is a chemical usually used as the chemical reagent and intermediate, such as being the intermediate for Levetiracetam, a medicine resisting epilepsia and convulsions.
Levetiracetam (chemical name (S)-2-(2-Oxopyrrolidin-1-yl)butanamide) is currently the only epilepsia resisting medicine that has been proven to combine with the synaptin SV2A inside the presynaptic nerve terminal. It can restrain the abnormal electro-discharge in the epilepsia loop, and therefore block the seizures. It is used in the treatment of partial, secondary and general epilepsia.
Using L-2-Aminobutanamide hydrochloride as the chiral source for synthesis of Levetiracetam, the resolution of raceme could be avoided.
