(3-(Trifluoromethyl)phenyl)methanethiol (CAS 25697-55-6) is a high-purity analytical reference standard with the molecular formula C8H7F3S and a molecular weight of 192.20 g/mol.
Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, (3-(Trifluoromethyl)phenyl)methanethiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), (3-(Trifluoromethyl)phenyl)methanethiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
