2-(2,4-Dichlorophenoxy)-1-(3,5-dimethyl-1H-pyrazol-1-yl)ethanone CAS 13241-78-6

Description

2-(2,4-Dichlorophenoxy)-1-(3,5-dimethyl-1H-pyrazol-1-yl)ethanone (CAS 13241-78-6), molecular formula C13H12Cl2N2O2 and molecular weight 299.15 g/mol, is a CATO reference standard with documented purity and traceability.

2-(2,4-Dichlorophenoxy)-1-(3,5-dimethyl-1H-pyrazol-1-yl)ethanone (C13H12Cl2N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
