Chemical Structure
Description
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.
3-Chloro-N-(4-((trifluoromethyl)thio)phenyl)naphtho[1,2-b]thiophene-2-carboxamide (CAS 1024316-70-8) is a high-purity analytical reference standard with the molecular formula C20H11ClF3NOS2 and a molecular weight of 437.89 g/mol.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 3-Chloro-N-(4-((trifluoromethyl)thio)phenyl)naphtho[1,2-b]thiophene-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 437.89 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.
