Chemical Structure
Description
The occurrence of 1,1,2,2-Tetrachloro-1,2-dimethyldisilane is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,1,2,2-Tetrachloro-1,2-dimethyldisilane (CAS 4518-98-3), a certified reference material (molecular formula C2H6Cl4Si2, MW 228.05 g/mol) for analytical method development and quality control.
Owing to chlorine substitution, 1,1,2,2-Tetrachloro-1,2-dimethyldisilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
