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.
2,2-diethoxypropane (CAS 126-84-1), molecular formula C7H16O2 and molecular weight 132.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2,2-diethoxypropane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
