Chemical Structure
Description
The occurrence of Benzyl 2-Acetamido-2-deoxy-3-O-(β-D-galactopyranosyl)-4,6-benzylidene-α-D-galactoside is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Benzyl 2-Acetamido-2-deoxy-3-O-(β-D-galactopyranosyl)-4,6-benzylidene-α-D-galactoside (CAS 90754-58-8), molecular formula C28H35NO11 and molecular weight 561.58 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Benzyl 2-Acetamido-2-deoxy-3-O-(β-D-galactopyranosyl)-4,6-benzylidene-α-D-galactoside (C28H35NO11) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
