Compared with other compounds in its class, the molecular weight of 639.93 g/mol gives 1,1′-[(2,3,5,6-Tetrafluoro-1,4-phenylene)di-5,2-thiophenediyl]bis[1,1,1-trimethylstannane] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,1′-[(2,3,5,6-Tetrafluoro-1,4-phenylene)di-5,2-thiophenediyl]bis[1,1,1-trimethylstannane] (CAS 1449302-74-2), a certified reference material (molecular formula C20H22F4S2Sn2, MW 639.93 g/mol) for analytical method development and quality control.
1,1′-[(2,3,5,6-Tetrafluoro-1,4-phenylene)di-5,2-thiophenediyl]bis[1,1,1-trimethylstannane] (C20H22F4S2Sn2) contains sulfur-containing functionality, fluorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
