(4Z)-4-({[(4-chlorophenyl)methyl]amino}methylidene)-1-methyl-3-(trifluoromethyl)-4,5-dihydro-1H-pyrazol-5-one CAS 320425-19-2

Description

(4Z)-4-({[(4-chlorophenyl)methyl]amino}methylidene)-1-methyl-3-(trifluoromethyl)-4,5-dihydro-1H-pyrazol-5-one (C13H11ClF3N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

(4Z)-4-({[(4-chlorophenyl)methyl]amino}methylidene)-1-methyl-3-(trifluoromethyl)-4,5-dihydro-1H-pyrazol-5-one (CAS 320425-19-2), molecular formula C13H11ClF3N3O and molecular weight 317.69 g/mol, is a CATO reference standard with documented purity and traceability.

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.
