Description
CATO manufactures Ethyl 4-(2-methylphenyl)-2,4-dioxobutanoate 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.
CATO supplies Ethyl 4-(2-methylphenyl)-2,4-dioxobutanoate (CAS 741286-44-2), a certified reference material (molecular formula C13H14O4, MW 234.25 g/mol) for analytical method development and quality control.
Ethyl 4-(2-methylphenyl)-2,4-dioxobutanoate (C13H14O4) contains 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.
