Chemical Structure

((2R,3R,4S,5R,6S)-3,4,5-tris(benzyloxy)-6-(4-methoxyphenoxy)tetrahydro-2H-pyran-2-yl)methanol CAS 1055325-21-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ((2R,3R,4S,5R,6S)-3,4,5-tris(benzyloxy)-6-(4-methoxyphenoxy)tetrahydro-2H-pyran-2-yl)methanol.

CATO supplies ((2R,3R,4S,5R,6S)-3,4,5-tris(benzyloxy)-6-(4-methoxyphenoxy)tetrahydro-2H-pyran-2-yl)methanol (CAS 1055325-21-7), a certified reference material (molecular formula C34H36O7, MW 556.65 g/mol) for analytical method development and quality control.

((2R,3R,4S,5R,6S)-3,4,5-tris(benzyloxy)-6-(4-methoxyphenoxy)tetrahydro-2H-pyran-2-yl)methanol (C34H36O7) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), ((2R,3R,4S,5R,6S)-3,4,5-tris(benzyloxy)-6-(4-methoxyphenoxy)tetrahydro-2H-pyran-2-yl)methanol 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.
