Chemical Structure
Description
The occurrence of 1,2:5,6-Di-O-isopropylidene-α-D-ribo-hexofuranose-3-ulose (mixture of keto and ketal forms) is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,2:5,6-Di-O-isopropylidene-α-D-ribo-hexofuranose-3-ulose (mixture of keto and ketal forms) (CAS 2847-00-9), molecular formula C12H18O6 and molecular weight 258.27 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H18O6, 1,2:5,6-Di-O-isopropylidene-α-D-ribo-hexofuranose-3-ulose (mixture of keto and ketal forms) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
