2-Chloro-n-[3-(4-methylphenyl)-1-phenyl-1h-pyrazol-5-yl]acetamide (CAS 956262-31-0) is a high-purity analytical reference standard with the molecular formula C18H16ClN3O and a molecular weight of 325.79 g/mol.
The molecular framework of 2-Chloro-n-[3-(4-methylphenyl)-1-phenyl-1h-pyrazol-5-yl]acetamide (C18H16ClN3O) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
