Cyclopropyl(3-(1-((2-fluoro-[1,1'-biphenyl]-4-yl)oxy)ethyl)-1H-pyrazol-1-yl)methanone CAS 477709-65-2 chemical structure

Description

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.

Cyclopropyl(3-(1-((2-fluoro-[1,1'-biphenyl]-4-yl)oxy)ethyl)-1H-pyrazol-1-yl)methanone (CAS 477709-65-2), molecular formula C21H19FN2O2 and molecular weight 350.39 g/mol, is a CATO reference standard with documented purity and traceability.

Cyclopropyl(3-(1-((2-fluoro-[1,1'-biphenyl]-4-yl)oxy)ethyl)-1H-pyrazol-1-yl)methanone (C21H19FN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
