Descrizione generale

2-Ethyl-2-hydroxybutyric acid forms 99mTc complexes.

Applicazioni

2-Ethyl-2-hydroxybutyric acid was used as internal standard during quantification of medium-chain-length bacterial poly(3-hydroxyalkanoate) by gas chromatography. It was used as ligand to study the effect of anionic and cationic surfactants on kinetics of electron transfer reaction from organic sulfides to [CrV(ehba)2]- (ehba=2-ethyl-2-hydroxy butyric acid).

99mTc complexes of 2-ethyl-2-hydrobutyric acid, 2-hydroxyisobutyric acid and (+)- and (-)-citramalic acid are readily prepared in high yield and high purity by reduction of 99mTcO4- in the presence of excess ligand. The resulting agents are very stable in vitro, but

Standard chromatographic methods for the quantification of bacterial poly(3-hydroxyalkanoate) (PHA) proved to be inappropriate for the analysis of medium-chain-length PHA (mcl-PHA). Transesterification catalyzed by protic acids is not quantitative for mcl-PHA under common conditions due to slow reaction kinetics and
