Chemical Structure

2-Propenoic acid, polymer with 2,2'-oxybis[ethanol], potassium salt CAS 67906-94-9 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-Propenoic acid, polymer with 2,2'-oxybis[ethanol], potassium salt (CAS 67906-94-9), molecular formula C4H9O3C3H4O2K and molecular weight 216.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-Propenoic acid, polymer with 2,2'-oxybis[ethanol], potassium salt (C4H9O3C3H4O2K) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 216.27 g/mol, it falls into the medium-molecular-weight range.

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.
