Chemical Structure
Description
The molecular framework of Methyl 2-3-6-tri-O-acetyl-4-deoxy-4-fluoro-α-D-galactopyranoside (C13H19FO8) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
CATO supplies Methyl 2-3-6-tri-O-acetyl-4-deoxy-4-fluoro-α-D-galactopyranoside (CAS 32934-08-0), a certified reference material (molecular formula C13H19FO8, MW 322.28 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.
