Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 338.11 g/mol gives 4-(2-(Trichlorosilyl)ethyl)benzenesulfonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(2-(Trichlorosilyl)ethyl)benzenesulfonyl chloride (CAS 79793-00-3), molecular formula C8H8Cl4O2SSi and molecular weight 338.11 g/mol, is a CATO reference standard with documented purity and traceability.
4-(2-(Trichlorosilyl)ethyl)benzenesulfonyl chloride (C8H8Cl4O2SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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.
