Chemical Structure
Description
2-chloro-1,1,1,3,3,3-hexamethyl-2-(trimethylsilyl)trisilane 5565-32-2 Chlorotris(trimethylsilyl)silane (CAS 5565-32-2) is a high-purity analytical reference standard with the molecular formula C9H27ClSi4 and a molecular weight of 283.11 g/mol.
2-chloro-1,1,1,3,3,3-hexamethyl-2-(trimethylsilyl)trisilane 5565-32-2 Chlorotris(trimethylsilyl)silane (C9H27ClSi4) contains chlorine substitution. Halogen substitution raises its density and boiling point; 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.
