Chemical Structure
Description
CATO supplies 2-4-7-8-9-Penta-O-acetyl N-acetylneuraminic acid (CAS 4887-11-0), a certified reference material (molecular formula C21H29NO14, MW 519.45 g/mol) for analytical method development and quality control.
2-4-7-8-9-Penta-O-acetyl N-acetylneuraminic acid (C21H29NO14) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 2-4-7-8-9-Penta-O-acetyl N-acetylneuraminic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
