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 1,1,2,2,3,3-Hexafluoropropane-1,3-disulfonimide.
Potassium 1,1,2,2,3,3-Hexafluoropropane-1,3-disulfonimide (CAS 588668-97-7), molecular formula C3F6KNO4S2 and molecular weight 331.26 g/mol, is a CATO reference standard with documented purity and traceability.
Potassium 1,1,2,2,3,3-Hexafluoropropane-1,3-disulfonimide (C3F6KNO4S2) contains an amide group, a sulfone group, a carboxylic acid group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 1,1,2,2,3,3-Hexafluoropropane-1,3-disulfonimide 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.
