Chemical Structure
Description
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.
CATO supplies (4-Chloro-2-fluorophenyl)trimethylsilane (CAS 153357-87-0), a certified reference material (molecular formula C9H12ClFSi, MW 202.73 g/mol) for analytical method development and quality control.
Owing to fluorine/chlorine substitution, (4-Chloro-2-fluorophenyl)trimethylsilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.73 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
