Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5-Amino-1-(4-methoxyphenyl)-1H-pyrazol-4-yl)(4-chlorophenyl)methanone.
CATO supplies (5-Amino-1-(4-methoxyphenyl)-1H-pyrazol-4-yl)(4-chlorophenyl)methanone (CAS 618091-17-1), a certified reference material (molecular formula C17H14ClN3O2, MW 327.76 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (5-Amino-1-(4-methoxyphenyl)-1H-pyrazol-4-yl)(4-chlorophenyl)methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 327.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
