(5-Amino-1-(4-chlorophenyl)-1H-pyrazol-4-yl)(p-tolyl)methanone CAS 618091-23-9

Description

The molecular framework of (5-Amino-1-(4-chlorophenyl)-1H-pyrazol-4-yl)(p-tolyl)methanone (C17H14ClN3O) 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. 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).

CATO supplies (5-Amino-1-(4-chlorophenyl)-1H-pyrazol-4-yl)(p-tolyl)methanone (CAS 618091-23-9), a certified reference material (molecular formula C17H14ClN3O, MW 311.77 g/mol) for analytical method development and quality control.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
