Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Amino-N-(2,6-dimethylphenyl)-4,6-diphenylthieno[2,3-b]pyridine-2-carboxamide (CAS 332040-35-4), molecular formula C28H23N3OS and molecular weight 449.57 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Amino-N-(2,6-dimethylphenyl)-4,6-diphenylthieno[2,3-b]pyridine-2-carboxamide (C28H23N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 449.57 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
