3-{3-[(2-chloro-6-fluorophenyl)methoxy]phenyl}-1-(4-fluorobenzenesulfonyl)-1H-pyrazole CAS 477712-71-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-{3-[(2-chloro-6-fluorophenyl)methoxy]phenyl}-1-(4-fluorobenzenesulfonyl)-1H-pyrazole.

3-{3-[(2-chloro-6-fluorophenyl)methoxy]phenyl}-1-(4-fluorobenzenesulfonyl)-1H-pyrazole (CAS 477712-71-3), molecular formula C22H15ClF2N2O3S and molecular weight 460.88 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C22H15ClF2N2O3S, 3-{3-[(2-chloro-6-fluorophenyl)methoxy]phenyl}-1-(4-fluorobenzenesulfonyl)-1H-pyrazole contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 460.88 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
