6-Methyl-2-(trifluoromethyl)-4H-chromene-4-thione (CAS 869985-99-9), molecular formula C11H7F3OS and molecular weight 244.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Methyl-2-(trifluoromethyl)-4H-chromene-4-thione (C11H7F3OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
