Description
CATO manufactures Ethyl (4-(methylthio)phenethyl) oxalate 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.
Ethyl (4-(methylthio)phenethyl) oxalate (CAS 1443313-68-5) is a high-purity analytical reference standard with the molecular formula C13H16O4S and a molecular weight of 268.33 g/mol.
Ethyl (4-(methylthio)phenethyl) oxalate (C13H16O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
