Chemical Structure
Description
Ethyl 2-(2-(4-chlorophenoxy)acetamido)-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate (CAS 352687-89-9), molecular formula C20H22ClNO4S and molecular weight 407.91 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 2-(2-(4-chlorophenoxy)acetamido)-5,6,7,8-tetrahydro-4H-cyclohepta[b]thiophene-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 407.91 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
