3-Amino-4-(3,4-dimethylphenyl)-6-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide CAS 828280-24-6

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-Amino-4-(3,4-dimethylphenyl)-6-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide (CAS 828280-24-6), molecular formula C17H14F3N3OS and molecular weight 365.37 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 3-Amino-4-(3,4-dimethylphenyl)-6-(trifluoromethyl)thieno[2,3-b]pyridine-2-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 365.37 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
