Chemical Structure
Description
As a certified reference material (CRM), 4-O-(6-O-[2-Acetamido-2-deoxy-b-D-glucopyranosyl]-b-D-galactopyranosyl)-D-glucopyranose meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-O-(6-O-[2-Acetamido-2-deoxy-b-D-glucopyranosyl]-b-D-galactopyranosyl)-D-glucopyranose (CAS 68665-69-0), molecular formula C20H35NO16 and molecular weight 545.49 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-O-(6-O-[2-Acetamido-2-deoxy-b-D-glucopyranosyl]-b-D-galactopyranosyl)-D-glucopyranose is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 545.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
