Description

Compared with other compounds in its class, the molecular weight of 341.41 g/mol gives 4-((1-Methyl-3,5-diphenyl-1H-pyrazol-4-yl)oxy)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-((1-Methyl-3,5-diphenyl-1H-pyrazol-4-yl)oxy)aniline (CAS 60628-10-6), molecular formula C22H19N3O and molecular weight 341.41 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-((1-Methyl-3,5-diphenyl-1H-pyrazol-4-yl)oxy)aniline (C22H19N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 341.41 g/mol, it falls into the moderately-high-molecular-weight range. 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.
