Description
Compared with other compounds in its class, the molecular weight of 387.52 g/mol gives Isopropyl 3-amino-6-methyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydrothieno[2,3-b][1,6]naphthyridine-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Isopropyl 3-amino-6-methyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydrothieno[2,3-b][1,6]naphthyridine-2-carboxylate (CAS 445384-47-4) is a high-purity analytical reference standard with the molecular formula C19H21N3O2S2 and a molecular weight of 387.52 g/mol.
Structurally, Isopropyl 3-amino-6-methyl-4-(thiophen-2-yl)-5,6,7,8-tetrahydrothieno[2,3-b][1,6]naphthyridine-2-carboxylate (C19H21N3O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 387.52 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
