Chemical Structure
Description
Ethyl (2E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]sulfanyl}-3-[(4-iodophenyl)amino]prop-2-enoate (CAS 338966-83-9) is a high-purity analytical reference standard with the molecular formula C17H13ClF3IN2O2S and a molecular weight of 528.72 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution, Ethyl (2E)-2-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]sulfanyl}-3-[(4-iodophenyl)amino]prop-2-enoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 528.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
