Chemical Structure
Description
4-Nitrophenyl 2-O-(α-L-Fucopyranosyl)-α-D-galactopyranoside (C18H25NO12) 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.
CATO supplies 4-Nitrophenyl 2-O-(α-L-Fucopyranosyl)-α-D-galactopyranoside (CAS 383417-46-7), a certified reference material (molecular formula C18H25NO12, MW 447.39 g/mol) for analytical method development and quality control.
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.
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.
