Description

The occurrence of (3AR,5R,6R,7S,7aR)-6,7-bis(benzyloxy)-5-((benzyloxy)methyl)-2-methoxy-2-methyltetrahydro-5H-[1,3]dioxolo[4,5-b]pyran 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.

(3AR,5R,6R,7S,7aR)-6,7-bis(benzyloxy)-5-((benzyloxy)methyl)-2-methoxy-2-methyltetrahydro-5H-[1,3]dioxolo[4,5-b]pyran (CAS 51532-75-3) is a high-purity analytical reference standard with the molecular formula C30H34O7 and a molecular weight of 506.59 g/mol.

The molecular framework of (3AR,5R,6R,7S,7aR)-6,7-bis(benzyloxy)-5-((benzyloxy)methyl)-2-methoxy-2-methyltetrahydro-5H-[1,3]dioxolo[4,5-b]pyran (C30H34O7) 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).

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), (3AR,5R,6R,7S,7aR)-6,7-bis(benzyloxy)-5-((benzyloxy)methyl)-2-methoxy-2-methyltetrahydro-5H-[1,3]dioxolo[4,5-b]pyran 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.
