Chemical Structure

3,3-Difluorotetrahydrothiophene 1,1-dioxide CAS 779355-86-1 chemical structure

Description

As a certified reference material (CRM), 3,3-Difluorotetrahydrothiophene 1,1-dioxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

3,3-Difluorotetrahydrothiophene 1,1-dioxide (CAS 779355-86-1) is a high-purity analytical reference standard with the molecular formula C4H6F2O2S and a molecular weight of 156.15 g/mol.

3,3-Difluorotetrahydrothiophene 1,1-dioxide (C4H6F2O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.

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.
