Chemical Structure
Description
Bis(methyldifluorosilyl)ethane (CAS 170381-99-4), molecular formula C4H10F4Si2 and molecular weight 190.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Bis(methyldifluorosilyl)ethane (C4H10F4Si2) is characterized by fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
