Chemical Structure

Ethyl 2-amino-4-(4-tert-butylphenyl)-5-methylthiophene-3-carboxylate CAS 350989-72-9 chemical structure

Description

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 2-amino-4-(4-tert-butylphenyl)-5-methylthiophene-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 317.45 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.
