Chemical Structure
Description
The occurrence of Methyl 2-acetamido-2-deoxy-4-6-anisolydene-3-O-[b-D- (2-3-4-6-tetra-O-acetyl) galactopyranosyl]-α-D-galactopyranoside is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 2-acetamido-2-deoxy-4-6-anisolydene-3-O-[b-D- (2-3-4-6-tetra-O-acetyl) galactopyranosyl]-α-D-galactopyranoside (CAS 316139-74-9), molecular formula C31H41NO16 and molecular weight 683.65 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 2-acetamido-2-deoxy-4-6-anisolydene-3-O-[b-D- (2-3-4-6-tetra-O-acetyl) galactopyranosyl]-α-D-galactopyranoside (C31H41NO16) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
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.
