Chemical Structure
Description
The occurrence of 2-(5-Iodothiophen-2-yl)ethanol is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(5-Iodothiophen-2-yl)ethanol (CAS 918440-92-3), a certified reference material (molecular formula C6H7IOS, MW 254.09 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution, 2-(5-Iodothiophen-2-yl)ethanol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 254.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
