Chemical Structure
Description
2,4,7,8,9-Penta-O-acetyl-N-acetylneuraminic acid methyl ester, 97% (CAS 73208-82-9) is a high-purity analytical reference standard with the molecular formula C22H31NO14 and a molecular weight of 533.48 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 2,4,7,8,9-Penta-O-acetyl-N-acetylneuraminic acid methyl ester, 97% is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 533.48 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.
As a certified reference material (CRM), 2,4,7,8,9-Penta-O-acetyl-N-acetylneuraminic acid methyl ester, 97% 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.
