Chemical Structure

2,3-O-Isopropylidene-1,6-ditosyl-L-sorbose CAS 2484-55-1 chemical structure

Description

Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, 2,3-O-Isopropylidene-1,6-ditosyl-L-sorbose is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 528.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

2,3-O-Isopropylidene-1,6-ditosyl-L-sorbose (CAS 2484-55-1), molecular formula C23H28O10S2 and molecular weight 528.59 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
