Chemical Structure

H-Glu(Leu-OH)-OH CAS 2566-39-4 chemical structure

Description

Structurally, H-Glu(Leu-OH)-OH (C11H20N2O5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 260.29 g/mol, it falls into the medium-molecular-weight range. 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).

H-Glu(Leu-OH)-OH (CAS 2566-39-4) is a high-purity analytical reference standard with the molecular formula C11H20N2O5 and a molecular weight of 260.29 g/mol.
