Chemical Structure
Description
The occurrence of Caesium tris(trifluoromethanesulphonyl)methide is closely related to a carbohydrate-derived structure, a sulfone group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Caesium tris(trifluoromethanesulphonyl)methide (CAS 114395-68-5), molecular formula C4F9O6S3Cs and molecular weight 544.11 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Caesium tris(trifluoromethanesulphonyl)methide (C4F9O6S3Cs) contains a carbohydrate-derived structure, a sulfone group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 544.11 g/mol, it falls into the moderately-high-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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
