6-Bromo-4-methyl-1-phenyl-3H-naphtho[1,2,3-de]quinoline-2,7-dione (CAS 67499-52-9), molecular formula C23H14BrNO2 and molecular weight 416.27 g/mol, is a CATO reference standard with documented purity and traceability.
6-Bromo-4-methyl-1-phenyl-3H-naphtho[1,2,3-de]quinoline-2,7-dione (C23H14BrNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 6-Bromo-4-methyl-1-phenyl-3H-naphtho[1,2,3-de]quinoline-2,7-dione 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.
