Chemical Structure
Description
As a certified reference material (CRM), 2-3-O-Isopropylidene-5-O-trityl-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.
2-3-O-Isopropylidene-5-O-trityl-D-ribofuranose (CAS 55726-19-7), molecular formula C27H28O5 and molecular weight 432.51 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, 2-3-O-Isopropylidene-5-O-trityl-D-ribofuranose is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 432.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
