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.

1,​1,​1-​Trifluoro-​N-​[(11bS)​-​4-​oxido-​2,​6-​bis[2,​4,​6-​trisisopropylphenyl]​dinaphtho[2,​1-​d:1',​2'-​f]​[1,​3,​2]​dioxaphosphepin-​4-​yl]​methanesulfonamide (CAS 908338-43-2), molecular formula C51H57F3NO5PS and molecular weight 884.04 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C51H57F3NO5PS, 1,​1,​1-​Trifluoro-​N-​[(11bS)​-​4-​oxido-​2,​6-​bis[2,​4,​6-​trisisopropylphenyl]​dinaphtho[2,​1-​d:1',​2'-​f]​[1,​3,​2]​dioxaphosphepin-​4-​yl]​methanesulfonamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 884.04 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).

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.
