Description

The occurrence of Methyl 2,3,4-tri-O-benzoyl-6-O-triisopropylsilyl-a-D-galactopyranoside 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.

Methyl 2,3,4-tri-O-benzoyl-6-O-triisopropylsilyl-a-D-galactopyranoside (CAS 356060-82-7), molecular formula C37H46O9Si and molecular weight 662.84 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Methyl 2,3,4-tri-O-benzoyl-6-O-triisopropylsilyl-a-D-galactopyranoside (C37H46O9Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 662.84 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
