Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 229.29 g/mol gives Dichlorobis(trimethylsilyl)methane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dichlorobis(trimethylsilyl)methane (CAS 15951-41-4) is a high-purity analytical reference standard with the molecular formula C7H18Cl2Si2 and a molecular weight of 229.29 g/mol.
Structurally, Dichlorobis(trimethylsilyl)methane (C7H18Cl2Si2) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -2.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 229.29 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
