Chemical Structure

O-2,3,4,6-Tetra-O-acetyl-alpha-D-glucopyranosyl-(1-4)-O-2,3,6-tri-O-acetyl-alpha-D-glucopyranosyl-(1-4)-alpha-D-Glucopyranosyl Bromide Triacetate CAS 60438-67-7 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, O-2,3,4,6-Tetra-O-acetyl-alpha-D-glucopyranosyl-(1-4)-O-2,3,6-tri-O-acetyl-alpha-D-glucopyranosyl-(1-4)-alpha-D-Glucopyranosyl Bromide Triacetate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 987.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
