Chemical Structure
Description
Owing to chlorine substitution, Trichloro(4-(chloromethyl)phenyl)silane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.02 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.
Trichloro(4-(chloromethyl)phenyl)silane (CAS 13688-90-9) is a high-purity analytical reference standard with the molecular formula C7H6Cl4Si and a molecular weight of 260.02 g/mol.
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.
