Chemical Structure
Description
The occurrence of 2,4,7,8,9-Pentaacetyl-D-N-acetylglycolylneuraminic Acid Methyl Ester is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,4,7,8,9-Pentaacetyl-D-N-acetylglycolylneuraminic Acid Methyl Ester (CAS 118865-38-6), molecular formula C24H33NO16 and molecular weight 591.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,4,7,8,9-Pentaacetyl-D-N-acetylglycolylneuraminic Acid Methyl Ester (C24H33NO16) 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 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).
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.
As a certified reference material (CRM), 2,4,7,8,9-Pentaacetyl-D-N-acetylglycolylneuraminic Acid Methyl Ester 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.
