Chemical Structure
Description
CATO supplies 2-Bromo-1-(2,5-dimethylthiophen-3-yl)ethan-1-one (CAS 122654-17-5), a certified reference material (molecular formula C8H9BrOS, MW 233.13 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H9BrOS, 2-Bromo-1-(2,5-dimethylthiophen-3-yl)ethan-1-one contains sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 233.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
