Chemical Structure
Description
2-((3-((3-Chlorophenyl)carbamoyl)phenyl)carbamoyl)benzoic acid (CAS 307338-57-4) is a high-purity analytical reference standard with the molecular formula C21H15ClN2O4 and a molecular weight of 394.81 g/mol.
2-((3-((3-Chlorophenyl)carbamoyl)phenyl)carbamoyl)benzoic acid (C21H15ClN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
As a certified reference material (CRM), 2-((3-((3-Chlorophenyl)carbamoyl)phenyl)carbamoyl)benzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
