Barbituricacid (BA) may be used in the preparation of the corresponding hemiaminals, via chemoselective reduction in the presence of SmI2/H2O reagent. It may be used in the preparation of BA- modified conjugated carbon nitride nanosheets. Barbituricacid is a useful acid for organic and drug syntheses. Its dihydrate form can be synthesized from barbituricacid via crystallization from aqueous solution. Crystal structure of barbituricacid (in tautomeric form) has been investigated by a three dimensional fourier transform method. Its enol crystal form has been reported to be thermodynamically stable.

Barbital (BSA)
Barbiturates are a class of around 12 compounds derivatized from barbituricacid. They are central nervous system (CNS) depressants and can be used as sedatives, hypnotics, anaesthetics and anti-epileptic drugs. Barbiturates can be divided into three main groups according to their duration of action. The ultra-short-acting barbiturates are used clinically as anaesthetics while the long-acting barbiturates have anti-convulsant properties. The short-acting compounds are typically used as hypnotics. The short-acting barbiturates are extensively metabolised by the liver to more pharmacologically inactive hydroxylated compounds. Only a small proportion of parent compound (<0.2%) appears in the urine collected after 24 hours. However, with large doses, there is usually sufficient of the parent compound present to give an adequate response and some of the hydroxylated metabolites will also crossreact in immunoassays.
