Dimethyl 2-benzylmalonate (CAS 65749-05-5), molecular formula C12H14O4 and molecular weight 222.24 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H14O4, Dimethyl 2-benzylmalonate contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 222.24 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.
CATO manufactures Dimethyl 2-benzylmalonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
