Chemical Structure

(R)-1-((4R,5S)-2,2-Dimethyl-5-vinyl-1,3-dioxolan-4-yl)ethane-1,2-diol CAS 116780-31-5 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 (R)-1-((4R,5S)-2,2-Dimethyl-5-vinyl-1,3-dioxolan-4-yl)ethane-1,2-diol (CAS 116780-31-5), a certified reference material (molecular formula C9H16O4, MW 188.22 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (R)-1-((4R,5S)-2,2-Dimethyl-5-vinyl-1,3-dioxolan-4-yl)ethane-1,2-diol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.22 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.
