The occurrence of 9,12-Octadecadienoic acid (9Z,12Z)-, dimer, polymer with 2,2'-[(1-methylethylidene)bis(4,1-phenyleneoxymethylene)]bis[oxirane] and 2-methyl-2-propenoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
9,12-Octadecadienoic acid (9Z,12Z)-, dimer, polymer with 2,2'-[(1-methylethylidene)bis(4,1-phenyleneoxymethylene)]bis[oxirane] and 2-methyl-2-propenoic acid (CAS 68992-10-9), molecular formula C21H24O4C18H32O2C4H6O2 and molecular weight 706.96 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H24O4C18H32O2C4H6O2, 9,12-Octadecadienoic acid (9Z,12Z)-, dimer, polymer with 2,2'-[(1-methylethylidene)bis(4,1-phenyleneoxymethylene)]bis[oxirane] and 2-methyl-2-propenoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 706.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
