CATO supplies 1-(5-(2,4-Dichlorophenyl)-3-(furan-2-yl)-4,5-dihydro-1H-pyrazol-1-yl)-2-(pyrrolidin-1-yl)ethan-1-one (CAS 1016416-91-3), a certified reference material (molecular formula C19H19Cl2N3O2, MW 392.28 g/mol) for analytical method development and quality control.
The molecular framework of 1-(5-(2,4-Dichlorophenyl)-3-(furan-2-yl)-4,5-dihydro-1H-pyrazol-1-yl)-2-(pyrrolidin-1-yl)ethan-1-one (C19H19Cl2N3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-(5-(2,4-Dichlorophenyl)-3-(furan-2-yl)-4,5-dihydro-1H-pyrazol-1-yl)-2-(pyrrolidin-1-yl)ethan-1-one 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.
