2-Propenoic acid, 3,3'-(1,4-phenylene)bis-, 1,1'-diethyl ester, polymer with 2,2'-[1,4-cyclohexanediylbis(oxy)]bis[ethanol] CAS 32630-58-3

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.

2-Propenoic acid, 3,3'-(1,4-phenylene)bis-, 1,1'-diethyl ester, polymer with 2,2'-[1,4-cyclohexanediylbis(oxy)]bis[ethanol] (CAS 32630-58-3), molecular formula C16H18O4C10H20O4 and molecular weight 478.58 g/mol, is a CATO reference standard with documented purity and traceability.

2-Propenoic acid, 3,3'-(1,4-phenylene)bis-, 1,1'-diethyl ester, polymer with 2,2'-[1,4-cyclohexanediylbis(oxy)]bis[ethanol] (C16H18O4C10H20O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
