The occurrence of 4-Fluorothiophenolpotassiumsalt is closely related to sulfur-containing functionality, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Fluorothiophenolpotassiumsalt (CAS 132130-83-7), molecular formula C6H4FKS and molecular weight 166.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, 4-Fluorothiophenolpotassiumsalt is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 4-Fluorothiophenolpotassiumsalt 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.
