The occurrence of 2-Butenedioic acid (2Z)-, 1-ethyl ester, polymer with ethenyl acetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Butenedioic acid (2Z)-, 1-ethyl ester, polymer with ethenyl acetate (CAS 26795-96-0), molecular formula C6H8O4C4H6O2 and molecular weight 230.22 g/mol, is a CATO reference standard with documented purity and traceability.
2-Butenedioic acid (2Z)-, 1-ethyl ester, polymer with ethenyl acetate (C6H8O4C4H6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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).
