Chemical Structure

3-Chloro-N-((3-(1-(4-fluorophenyl)-1H-pyrazol-3-yl)-4,5-dihydroisoxazol-5-yl)methyl)-5-(trifluoromethyl)pyridin-2-amine CAS 318951-75-6 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.

3-Chloro-N-((3-(1-(4-fluorophenyl)-1H-pyrazol-3-yl)-4,5-dihydroisoxazol-5-yl)methyl)-5-(trifluoromethyl)pyridin-2-amine (CAS 318951-75-6), molecular formula C19H14ClF4N5O and molecular weight 439.79 g/mol, is a CATO reference standard with documented purity and traceability.

3-Chloro-N-((3-(1-(4-fluorophenyl)-1H-pyrazol-3-yl)-4,5-dihydroisoxazol-5-yl)methyl)-5-(trifluoromethyl)pyridin-2-amine (C19H14ClF4N5O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; 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.
