Butanedioic acid, 2-methylene-, polymer with 1,3-butadiene and ethenylbenzene (CAS 30174-67-5), molecular formula C5H6O4C8H8C4H6 and molecular weight 288.34 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H6O4C8H8C4H6, Butanedioic acid, 2-methylene-, polymer with 1,3-butadiene and ethenylbenzene contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 288.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), Butanedioic acid, 2-methylene-, polymer with 1,3-butadiene and ethenylbenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
