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.
CATO supplies (4R,5R,6R)-4,5-Bis(benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-one (CAS 79999-46-5), a certified reference material (molecular formula C27H28O5, MW 432.51 g/mol) for analytical method development and quality control.
The molecular framework of (4R,5R,6R)-4,5-Bis(benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-one (C27H28O5) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (4R,5R,6R)-4,5-Bis(benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-one 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.
