Chemical Structure

Mono-2-O-(p-toluenesulfonyl)-α-cyclodextrin CAS 93184-10-2 chemical structure

Description

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.

Mono-2-O-(p-toluenesulfonyl)-α-cyclodextrin (CAS 93184-10-2), molecular formula C43H66O32S and molecular weight 1127.03 g/mol, is a CATO reference standard with documented purity and traceability.

Mono-2-O-(p-toluenesulfonyl)-α-cyclodextrin (C43H66O32S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
