1-3-4-6-Tetra-O-acetyl-2-O-(2-3-4-tri-O-benzoyl-α-L-fucopyranosyl)-α-D-galactopyranose CAS 141990-06-9 chemical structure

Description

The occurrence of 1-3-4-6-Tetra-O-acetyl-2-O-(2-3-4-tri-O-benzoyl-α-L-fucopyranosyl)-α-D-galactopyranose is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-3-4-6-Tetra-O-acetyl-2-O-(2-3-4-tri-O-benzoyl-α-L-fucopyranosyl)-α-D-galactopyranose (CAS 141990-06-9), molecular formula C41H42O17 and molecular weight 806.76 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1-3-4-6-Tetra-O-acetyl-2-O-(2-3-4-tri-O-benzoyl-α-L-fucopyranosyl)-α-D-galactopyranose is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 806.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
