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.
3-(Trichlorosilyl)propyl 2-Bromo-2-methylpropanoate (CAS 688359-84-4), molecular formula C7H12BrCl3O2Si and molecular weight 342.52 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 3-(Trichlorosilyl)propyl 2-Bromo-2-methylpropanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.52 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.
