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.
CATO supplies Methyl 3-(6-methoxy-1-(p-tolyl)-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-2-carboxamido)thiophene-2-carboxylate (CAS 931941-76-3), a certified reference material (molecular formula C26H25N3O4S, MW 475.56 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 3-(6-methoxy-1-(p-tolyl)-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-2-carboxamido)thiophene-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 475.56 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.
