Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 3-[4-(2,4-dichlorobenzoyl)-1-methyl-1H-pyrrol-2-yl]acrylate.
Ethyl 3-[4-(2,4-dichlorobenzoyl)-1-methyl-1H-pyrrol-2-yl]acrylate (CAS 400077-69-2), molecular formula C17H15Cl2NO3 and molecular weight 352.21 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 3-[4-(2,4-dichlorobenzoyl)-1-methyl-1H-pyrrol-2-yl]acrylate (C17H15Cl2NO3) contains a steroid core, 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. 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.
As a certified reference material (CRM), Ethyl 3-[4-(2,4-dichlorobenzoyl)-1-methyl-1H-pyrrol-2-yl]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.
