Chemical Structure
Description
CATO supplies Triethoxy(3-((perfluoropropan-2-yl)oxy)propyl)silane (CAS 149838-19-7), a certified reference material (molecular formula C12H21F7O4Si, MW 390.37 g/mol) for analytical method development and quality control.
Triethoxy(3-((perfluoropropan-2-yl)oxy)propyl)silane (C12H21F7O4Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
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.
