Chemical Structure
Description
Owing to a carbohydrate-derived structure, an amide group, <SC>L</SC>-Glutamic acid hemimagnesium salt tetrahydrate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
<SC>L</SC>-Glutamic acid hemimagnesium salt tetrahydrate (CAS 18543-68-5) is a high-purity analytical reference standard with the molecular formula C10H16MgN2O8H2O and a molecular weight of 334.56 g/mol.
