Description
Compared with other compounds in its class, the molecular weight of 282.12 g/mol gives 2,4-Dichloro-N-(2-hydroxyphenyl)benzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,4-Dichloro-N-(2-hydroxyphenyl)benzamide (CAS 54255-56-0), molecular formula C13H9Cl2NO2 and molecular weight 282.12 g/mol, is a CATO reference standard with documented purity and traceability.
2,4-Dichloro-N-(2-hydroxyphenyl)benzamide (C13H9Cl2NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,4-Dichloro-N-(2-hydroxyphenyl)benzamide 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.
