Chemical Structure
Description
7-(Trifluoromethyl)benzo[b]thiophene (CAS 120568-07-2) is a high-purity analytical reference standard with the molecular formula C9H5F3S and a molecular weight of 202.20 g/mol.
Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, 7-(Trifluoromethyl)benzo[b]thiophene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.20 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.
CATO manufactures 7-(Trifluoromethyl)benzo[b]thiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
