Chemical Structure
Description
Methyl 2-(2,4-dichloro-5-fluorobenzoyl)-3-((4-fluorophenyl)amino)acrylate (CAS 176637-98-2), molecular formula C17H11Cl2F2NO3 and molecular weight 386.18 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 2-(2,4-dichloro-5-fluorobenzoyl)-3-((4-fluorophenyl)amino)acrylate (C17H11Cl2F2NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Methyl 2-(2,4-dichloro-5-fluorobenzoyl)-3-((4-fluorophenyl)amino)acrylate 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.
