Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 292.35 g/mol gives Triethylsilyl 2,2-difluoro-2-(fluorosulfonyl)acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Triethylsilyl 2,2-difluoro-2-(fluorosulfonyl)acetate (CAS 757203-27-3), a certified reference material (molecular formula C8H15F3O4SSi, MW 292.35 g/mol) for analytical method development and quality control.
Triethylsilyl 2,2-difluoro-2-(fluorosulfonyl)acetate (C8H15F3O4SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl 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 Triethylsilyl 2,2-difluoro-2-(fluorosulfonyl)acetate 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.
