2-(4-Methylthiazol-2-yl)-5-(trifluoromethyl)aniline CAS 923946-06-9

Description

Compared with other compounds in its class, the molecular weight of 258.26 g/mol gives 2-(4-Methylthiazol-2-yl)-5-(trifluoromethyl)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(4-Methylthiazol-2-yl)-5-(trifluoromethyl)aniline (CAS 923946-06-9), molecular formula C11H9F3N2S and molecular weight 258.26 g/mol, is a CATO reference standard with documented purity and traceability.

2-(4-Methylthiazol-2-yl)-5-(trifluoromethyl)aniline (C11H9F3N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
