Chemical Structure

Methyl 6-O-Trityl-α-D-galactopyranoside CAS 35920-83-3 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 6-O-Trityl-α-D-galactopyranoside (CAS 35920-83-3), molecular formula C26H28O6 and molecular weight 436.50 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 6-O-Trityl-α-D-galactopyranoside (C26H28O6) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 6-O-Trityl-α-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.
