2,4,7,9-tetramethylbenzo[b]-1,8-naphthyridin-5-amine CAS 309726-06-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4,7,9-tetramethylbenzo[b]-1,8-naphthyridin-5-amine.

2,4,7,9-tetramethylbenzo[b]-1,8-naphthyridin-5-amine (CAS 309726-06-5) is a high-purity analytical reference standard with the molecular formula C16H17N3 and a molecular weight of 251.33 g/mol.

Structurally, 2,4,7,9-tetramethylbenzo[b]-1,8-naphthyridin-5-amine (C16H17N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 251.33 g/mol, it falls into the medium-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.
