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.
Diethyl (((4-bromophenyl)sulfonyl)methyl)phosphonate (CAS 27691-37-8) is a high-purity analytical reference standard with the molecular formula C11H16BrO5PS and a molecular weight of 371.18 g/mol.
Owing to a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Diethyl (((4-bromophenyl)sulfonyl)methyl)phosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 371.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
