CATO supplies 2-Propenoic acid, 2-methyl-, 2-methylpropyl ester, polymer with sodium 2-propenoate (CAS 67923-96-0), a certified reference material (molecular formula C8H14O2C3H3O2Na, MW 236.24 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Propenoic acid, 2-methyl-, 2-methylpropyl ester, polymer with sodium 2-propenoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
