Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium (5-chlorothiophen-2-yl)trifluoroborate.
Potassium (5-chlorothiophen-2-yl)trifluoroborate (CAS 1190883-05-6) is a high-purity analytical reference standard with the molecular formula C4H2BClF3SK and a molecular weight of 224.47 g/mol.
Owing to a salt form, sulfur-containing functionality, fluorine/chlorine substitution, Potassium (5-chlorothiophen-2-yl)trifluoroborate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.47 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 Potassium (5-chlorothiophen-2-yl)trifluoroborate 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.
