Chemical Structure
Description
6,8-Diiodo-3-(2-oxo-2-(thiophen-2-yl)ethyl)quinazolin-4(3H)-one (CAS 669762-29-2) is a high-purity analytical reference standard with the molecular formula C14H8I2N2O2S and a molecular weight of 522.10 g/mol.
Based on its molecular formula C14H8I2N2O2S, 6,8-Diiodo-3-(2-oxo-2-(thiophen-2-yl)ethyl)quinazolin-4(3H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 522.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
