1,4-Benzenedicarboxylic acid, polymer with 1,4-cyclohexanedimethanol, 1,3-dihydro-1,3-dioxo-5-isobenzofurancarboxylic acid, 2,2-dimethyl-1,3-propanediol and 12-hydroxyoctadecanoic acid (CAS 70833-61-3), molecular formula C18H36O3C9H4O5C8H6O4C8H16O2C5H12O2 and molecular weight 907.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,4-Benzenedicarboxylic acid, polymer with 1,4-cyclohexanedimethanol, 1,3-dihydro-1,3-dioxo-5-isobenzofurancarboxylic acid, 2,2-dimethyl-1,3-propanediol and 12-hydroxyoctadecanoic acid (C18H36O3C9H4O5C8H6O4C8H16O2C5H12O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
