Chemical Structure
Description
The occurrence of Ethyl 5-(2,4-dichlorophenyl)-2-[4-(4-methoxyphenyl)piperazin-1-yl]-1H-pyrrole-3-carboxylate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl 5-(2,4-dichlorophenyl)-2-[4-(4-methoxyphenyl)piperazin-1-yl]-1H-pyrrole-3-carboxylate (CAS 338396-55-7), a certified reference material (molecular formula C24H25Cl2N3O3, MW 474.38 g/mol) for analytical method development and quality control.
Ethyl 5-(2,4-dichlorophenyl)-2-[4-(4-methoxyphenyl)piperazin-1-yl]-1H-pyrrole-3-carboxylate (C24H25Cl2N3O3) contains a steroid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures Ethyl 5-(2,4-dichlorophenyl)-2-[4-(4-methoxyphenyl)piperazin-1-yl]-1H-pyrrole-3-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
