Chemical Structure
Description
bis(2-iodothiophen-3-yl)methanol (CAS 474416-59-6) is a high-purity analytical reference standard with the molecular formula C9H6I2OS2 and a molecular weight of 448.08 g/mol.
bis(2-iodothiophen-3-yl)methanol (C9H6I2OS2) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
