Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 272.20 g/mol gives Methyl 4-(3-(difluoromethoxy)phenyl)-2,4-dioxobutanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl 4-(3-(difluoromethoxy)phenyl)-2,4-dioxobutanoate (CAS 832741-03-4), a certified reference material (molecular formula C12H10F2O5, MW 272.20 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Methyl 4-(3-(difluoromethoxy)phenyl)-2,4-dioxobutanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 272.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures Methyl 4-(3-(difluoromethoxy)phenyl)-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.
