Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 285.16 g/mol gives Methyl 3-(bromomethyl)-1-benzothiophene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl 3-(bromomethyl)-1-benzothiophene-2-carboxylate (CAS 39811-69-3) is a high-purity analytical reference standard with the molecular formula C11H9BrO2S and a molecular weight of 285.16 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, Methyl 3-(bromomethyl)-1-benzothiophene-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
