Description

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.

Dimethyl(4-(prop-2-yn-1-ylamino)-3-(trifluoromethyl)phenyl)phosphine oxide (CAS 2903923-42-0) is a high-purity analytical reference standard with the molecular formula C12H13F3NOP and a molecular weight of 275.21 g/mol.

Structurally, Dimethyl(4-(prop-2-yn-1-ylamino)-3-(trifluoromethyl)phenyl)phosphine oxide (C12H13F3NOP) contains a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 275.21 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
