Description
CATO supplies Methyl 5-acetamido-4-7-8-9-tetra-O-acetyl-2-6-anhydro-3-5-dideoxy-D-glycero-D-galacto-non-2-enonate (CAS 73960-72-2), a certified reference material (molecular formula C20H27NO12, MW 473.43 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 5-acetamido-4-7-8-9-tetra-O-acetyl-2-6-anhydro-3-5-dideoxy-D-glycero-D-galacto-non-2-enonate (C20H27NO12) is characterized by a flavonoid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
