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 Ethyl 1-(4'-(5-amino-1-methyl-1H-pyrazol-3-yl)-[1,1'-biphenyl]-4-yl)cyclopropane-1-carboxylate.
CATO supplies Ethyl 1-(4'-(5-amino-1-methyl-1H-pyrazol-3-yl)-[1,1'-biphenyl]-4-yl)cyclopropane-1-carboxylate (CAS 2225878-57-7), a certified reference material (molecular formula C22H23N3O2, MW 361.44 g/mol) for analytical method development and quality control.
Based on its molecular formula C22H23N3O2, Ethyl 1-(4'-(5-amino-1-methyl-1H-pyrazol-3-yl)-[1,1'-biphenyl]-4-yl)cyclopropane-1-carboxylate contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 361.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
