CATO manufactures 3-Fluoropyridine-2(1H)-thione 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.
3-Fluoropyridine-2(1H)-thione (CAS 865663-90-7), molecular formula C5H4FNS and molecular weight 129.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, sulfur-containing functionality, fluorine substitution, 3-Fluoropyridine-2(1H)-thione is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 129.16 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.
