Chemical Structure
Description
As a certified reference material (CRM), Methyl 4-(2,4-dichlorobenzoyl)-1H-pyrrole-2-carboxylate 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.
CATO supplies Methyl 4-(2,4-dichlorobenzoyl)-1H-pyrrole-2-carboxylate (CAS 453557-85-2), a certified reference material (molecular formula C13H9Cl2NO3, MW 298.12 g/mol) for analytical method development and quality control.
Methyl 4-(2,4-dichlorobenzoyl)-1H-pyrrole-2-carboxylate (C13H9Cl2NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
