Description
CATO supplies 1,4-Difluoro-5,8-dihydroxy-9,10-anthracenedione (CAS 131401-54-2), a certified reference material (molecular formula C14H6F2O4, MW 276.19 g/mol) for analytical method development and quality control.
1,4-Difluoro-5,8-dihydroxy-9,10-anthracenedione (C14H6F2O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
CATO manufactures 1,4-Difluoro-5,8-dihydroxy-9,10-anthracenedione 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.
