Chemical Structure
Description
The molecular framework of 2,3-O-Isopropylidene-5-O-trityl-β-D-ribofuranose (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).
CATO supplies 2,3-O-Isopropylidene-5-O-trityl-β-D-ribofuranose (CAS 54503-65-0), a certified reference material (molecular formula C27H28O5, MW 432.51 g/mol) for analytical method development and quality control.
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), 2,3-O-Isopropylidene-5-O-trityl-β-D-ribofuranose 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.
