Chemical Structure

(1R,2S,3R,4R,5S,6r)-6-hydroxycyclohexane-1,2,3,4,5-pentayl pentakis(dihydrogen phosphate) CAS 20298-95-7 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.

(1R,2S,3R,4R,5S,6r)-6-hydroxycyclohexane-1,2,3,4,5-pentayl pentakis(dihydrogen phosphate) (CAS 20298-95-7), molecular formula C6H17O21P5 and molecular weight 580.06 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (1R,2S,3R,4R,5S,6r)-6-hydroxycyclohexane-1,2,3,4,5-pentayl pentakis(dihydrogen phosphate) (C6H17O21P5) is characterized by a carbohydrate-derived structure, a phosphate ester group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
