N1-[(Diphenylphosphoryl)(thien-2-yl)methyl]-3-(trifluoromethyl)aniline CAS 260437-23-8

Description

Compared with other compounds in its class, the molecular weight of 457.45 g/mol gives N1-[(Diphenylphosphoryl)(thien-2-yl)methyl]-3-(trifluoromethyl)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N1-[(Diphenylphosphoryl)(thien-2-yl)methyl]-3-(trifluoromethyl)aniline (CAS 260437-23-8), molecular formula C24H19F3NOPS and molecular weight 457.45 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N1-[(Diphenylphosphoryl)(thien-2-yl)methyl]-3-(trifluoromethyl)aniline (C24H19F3NOPS) contains a steroid core, an amide group, sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 457.45 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
