Description
CATO manufactures Potassium hexafluorosilicate 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.
Potassium hexafluorosilicate (CAS 16871-90-2), molecular formula FO3SiK and molecular weight 134.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Potassium hexafluorosilicate (FO3SiK) contains fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 134.18 g/mol, it falls into the low-molecular-weight range. 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.
