Chemical Structure

6-O-Sulfo-β-cyclodextrin sodium salt CAS 197587-31-8 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.

CATO supplies 6-O-Sulfo-β-cyclodextrin sodium salt (CAS 197587-31-8), a certified reference material (molecular formula C42H63O56S7Na, MW 1711.32 g/mol) for analytical method development and quality control.

6-O-Sulfo-β-cyclodextrin sodium salt (C42H63O56S7Na) contains a sulfone group, a carboxylic acid 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.
