Propan-2-yl 3-{3-amino-6-methyl-5H,6H,7H,8H-thieno[2,3-b]1,6-naphthyridin-2-yl}-3-oxopropanoate CAS 625371-50-8

Description

Propan-2-yl 3-{3-amino-6-methyl-5H,6H,7H,8H-thieno[2,3-b]1,6-naphthyridin-2-yl}-3-oxopropanoate (CAS 625371-50-8), molecular formula C17H21N3O3S and molecular weight 347.43 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Propan-2-yl 3-{3-amino-6-methyl-5H,6H,7H,8H-thieno[2,3-b]1,6-naphthyridin-2-yl}-3-oxopropanoate (C17H21N3O3S) 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 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 347.43 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).

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.

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.
