Chemical Structure
Description
2,3,6-Trifluorobenzenesulfonyl chloride (CAS 1017779-75-7), molecular formula C6H2ClF3O2S and molecular weight 230.59 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,3,6-Trifluorobenzenesulfonyl chloride (C6H2ClF3O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 230.59 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
