Chemical Structure
Description
CATO supplies Bis(2-iodothiophen-3-yl)methanone (CAS 474416-61-0), a certified reference material (molecular formula C9H4I2OS2, MW 446.07 g/mol) for analytical method development and quality control.
The molecular framework of Bis(2-iodothiophen-3-yl)methanone (C9H4I2OS2) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
