Chemical Structure
Description
The occurrence of Methyl 2,3,4-tri-O-acetyl-6-O-tert-butyldimethylsilyl-a-D-galactopyranoside is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Methyl 2,3,4-tri-O-acetyl-6-O-tert-butyldimethylsilyl-a-D-galactopyranoside (CAS 594841-23-3), a certified reference material (molecular formula C19H34O9Si, MW 434.55 g/mol) for analytical method development and quality control.
Structurally, Methyl 2,3,4-tri-O-acetyl-6-O-tert-butyldimethylsilyl-a-D-galactopyranoside (C19H34O9Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 434.55 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), Methyl 2,3,4-tri-O-acetyl-6-O-tert-butyldimethylsilyl-a-D-galactopyranoside meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
