Chemical Structure

1,2:3,5-Di-O-isopropylidene-α-D-xylofuranose CAS 20881-04-3 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,2:3,5-Di-O-isopropylidene-α-D-xylofuranose is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 230.26 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).

1,2:3,5-Di-O-isopropylidene-α-D-xylofuranose (CAS 20881-04-3), molecular formula C11H18O5 and molecular weight 230.26 g/mol, is a CATO reference standard with documented purity and traceability.

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.
