Chemical Properties

white crystalline powder or needles

Uses

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 [Cr^V(ehba)₂]^- (ehba=2-ethyl-2-hydroxy butyric acid).

Definition

ChEBI: 2-Ethyl-2-hydroxy-butyric acid is a hydroxy fatty acid.

General Description

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