Chemical Structure
Description
CATO supplies (Chloromethyl)methylbis(pentafluorophenyl)silane (CAS 77669-65-9), a certified reference material (molecular formula C14H5ClF10Si, MW 426.71 g/mol) for analytical method development and quality control.
Structurally, (Chloromethyl)methylbis(pentafluorophenyl)silane (C14H5ClF10Si) contains fluorine/chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 426.71 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
