Chemical Structure
Description
O-(a-L-Idopyranosyluronic Acid 2-Sulfate-(1-4)-2,5-anhydro-Mannitol-6-sulfate (CAS 69180-27-4) is a high-purity analytical reference standard with the molecular formula C12H20O17S2 and a molecular weight of 500.41 g/mol.
Structurally, O-(a-L-Idopyranosyluronic Acid 2-Sulfate-(1-4)-2,5-anhydro-Mannitol-6-sulfate (C12H20O17S2) contains a carbohydrate-derived structure, a sulfone group. 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 500.41 g/mol, it falls into the moderately-high-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).
