Chemical Structure
Description
The occurrence of 1-(3-Bromo-5-methylthiophen-2-yl)-2-chloroethan-1-one is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(3-Bromo-5-methylthiophen-2-yl)-2-chloroethan-1-one (CAS 1482239-39-3) is a high-purity analytical reference standard with the molecular formula C7H6BrClOS and a molecular weight of 253.54 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, 1-(3-Bromo-5-methylthiophen-2-yl)-2-chloroethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.54 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.
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.
