Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 298.33 g/mol gives Dimethyl 2,3-diphenylbutanedioate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dimethyl 2,3-diphenylbutanedioate (CAS 19020-59-8) is a high-purity analytical reference standard with the molecular formula C18H18O4 and a molecular weight of 298.33 g/mol.
The molecular framework of Dimethyl 2,3-diphenylbutanedioate (C18H18O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Dimethyl 2,3-diphenylbutanedioate 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.
