Chemical Structure
Description
The occurrence of 2-[(5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)formamido]-N-[4-(propan-2-yl)phenyl]acetamide 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.
2-[(5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)formamido]-N-[4-(propan-2-yl)phenyl]acetamide (CAS 956206-56-7), molecular formula C22H23ClN4O2 and molecular weight 410.90 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-[(5-Chloro-1-methyl-3-phenyl-1H-pyrazol-4-yl)formamido]-N-[4-(propan-2-yl)phenyl]acetamide (C22H23ClN4O2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
