Chemical Structure
Description
2-Chloro-1-(2,5-dichlorothiophen-3-yl)ethan-1-one (CAS 13668-93-4) is a high-purity analytical reference standard with the molecular formula C6H3Cl3OS and a molecular weight of 229.51 g/mol.
Based on its molecular formula C6H3Cl3OS, 2-Chloro-1-(2,5-dichlorothiophen-3-yl)ethan-1-one contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 229.51 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.
