Chemical Structure

((7R,8S,9S)-2,8,9-Trihydroxy-2-oxido-1,3,6-trioxa-2-phosphaspiro[4.4]nonan-7-yl)methyl dihydrogen phosphate CAS 141875-43-6 chemical structure

Description

CATO supplies ((7R,8S,9S)-2,8,9-Trihydroxy-2-oxido-1,3,6-trioxa-2-phosphaspiro[4.4]nonan-7-yl)methyl dihydrogen phosphate (CAS 141875-43-6), a certified reference material (molecular formula C6H12O11P2, MW 322.10 g/mol) for analytical method development and quality control.

Owing to a carbohydrate-derived structure, a phosphate ester group, ((7R,8S,9S)-2,8,9-Trihydroxy-2-oxido-1,3,6-trioxa-2-phosphaspiro[4.4]nonan-7-yl)methyl dihydrogen phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
