p-Tolyl 6-bromo-2-(4-bromophenyl)quinoline-4-carboxylate CAS 355421-58-8

Description

p-Tolyl 6-bromo-2-(4-bromophenyl)quinoline-4-carboxylate (CAS 355421-58-8), molecular formula C23H15Br2NO2 and molecular weight 497.18 g/mol, is a CATO reference standard with documented purity and traceability.

p-Tolyl 6-bromo-2-(4-bromophenyl)quinoline-4-carboxylate (C23H15Br2NO2) 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 p-Tolyl 6-bromo-2-(4-bromophenyl)quinoline-4-carboxylate 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.
