Chemical Structure
Description
The occurrence of (S)-4-[5-Chloro-2-(isopropylamino)-4-pyridyl]-N-[1-(3-chlorophenyl)-2-hydroxyethyl]pyrrole-2-carboxamide 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 (S)-4-[5-Chloro-2-(isopropylamino)-4-pyridyl]-N-[1-(3-chlorophenyl)-2-hydroxyethyl]pyrrole-2-carboxamide (CAS 869886-67-9), a certified reference material (molecular formula C21H22Cl2N4O2, MW 433.33 g/mol) for analytical method development and quality control.
The molecular framework of (S)-4-[5-Chloro-2-(isopropylamino)-4-pyridyl]-N-[1-(3-chlorophenyl)-2-hydroxyethyl]pyrrole-2-carboxamide (C21H22Cl2N4O2) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 (S)-4-[5-Chloro-2-(isopropylamino)-4-pyridyl]-N-[1-(3-chlorophenyl)-2-hydroxyethyl]pyrrole-2-carboxamide 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.
