Chemical Structure

(4-Bromophenyl)(trimethylsilyl)methanone CAS 75748-11-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(4-Bromophenyl)(trimethylsilyl)methanone (CAS 75748-11-7) is a high-purity analytical reference standard with the molecular formula C10H13BrOSi and a molecular weight of 257.20 g/mol.

(4-Bromophenyl)(trimethylsilyl)methanone (C10H13BrOSi) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
