Chemical Structure

(2R,3S,4S,5R)-2-(Hydroxymethyl)-6-mercaptotetrahydro-2H-pyran-3,4,5-triol CAS 22566-82-1 chemical structure

Description

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.

CATO supplies (2R,3S,4S,5R)-2-(Hydroxymethyl)-6-mercaptotetrahydro-2H-pyran-3,4,5-triol (CAS 22566-82-1), a certified reference material (molecular formula C6H12O5S, MW 196.22 g/mol) for analytical method development and quality control.

(2R,3S,4S,5R)-2-(Hydroxymethyl)-6-mercaptotetrahydro-2H-pyran-3,4,5-triol (C6H12O5S) contains a carbohydrate-derived structure, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
