Chemical Structure
Description
CATO supplies 20442-70-0 Cesium 2,2-dimethylpropanoate Cesium pivalate Cesium trimethylacetate (CAS 20442-70-0), a certified reference material (molecular formula CsC5H9O2, MW 234.03 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 20442-70-0 Cesium 2,2-dimethylpropanoate Cesium pivalate Cesium trimethylacetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.03 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.
