Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 277.13 g/mol gives methyl 2-[(4-bromobenzene)sulfinyl]acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
methyl 2-[(4-bromobenzene)sulfinyl]acetate (CAS 63216-00-2) is a high-purity analytical reference standard with the molecular formula C9H9BrO3S and a molecular weight of 277.13 g/mol.
methyl 2-[(4-bromobenzene)sulfinyl]acetate (C9H9BrO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
