2-Hydroxyglutarate (2-hg) exists as enantiomers and can readily undergo cyclization to its lactone. Gas chromatography/electron ionization mass spectrometry (GC/EI-MS) has been used to separate 2-hg enantiomers in bodily fluids but the assay cannot simultaneously measure cyclic and acylic 2-hg enantiomers.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
