Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium trifluoro(2-methoxythiazol-5-yl)borate.
Potassium trifluoro(2-methoxythiazol-5-yl)borate (CAS 2221991-22-4), molecular formula C4H4BF3NOSK and molecular weight 221.04 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Potassium trifluoro(2-methoxythiazol-5-yl)borate (C4H4BF3NOSK) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Potassium trifluoro(2-methoxythiazol-5-yl)borate 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.
