Chemical Structure

Methyl 2,3,4-tri-O-benzyl-6-O-triisopropylsilyl-a-D-galactopyranoside CAS 162147-37-7 chemical structure

Description

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.

Methyl 2,3,4-tri-O-benzyl-6-O-triisopropylsilyl-a-D-galactopyranoside (CAS 162147-37-7), molecular formula C37H52O6Si and molecular weight 620.89 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 2,3,4-tri-O-benzyl-6-O-triisopropylsilyl-a-D-galactopyranoside (C37H52O6Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic 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 manufactures Methyl 2,3,4-tri-O-benzyl-6-O-triisopropylsilyl-a-D-galactopyranoside under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
