Description
CATO supplies 1-(4-Chlorophenyl)-3-(3-cyano-1-(4-methoxybenzyl)-4,5-dimethyl-1H-pyrrol-2-yl)urea (CAS 866017-64-3), a certified reference material (molecular formula C22H21ClN4O2, MW 408.88 g/mol) for analytical method development and quality control.
1-(4-Chlorophenyl)-3-(3-cyano-1-(4-methoxybenzyl)-4,5-dimethyl-1H-pyrrol-2-yl)urea (C22H21ClN4O2) 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 1-(4-Chlorophenyl)-3-(3-cyano-1-(4-methoxybenzyl)-4,5-dimethyl-1H-pyrrol-2-yl)urea 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.
