Methyl 4-6-di-O-acetyl-2-3-carbonyl-β-D-mannopyranoside (CAS 53958-22-8), molecular formula C12H16O9 and molecular weight 304.25 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 4-6-di-O-acetyl-2-3-carbonyl-β-D-mannopyranoside (C12H16O9) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
