Chemical Structure

6-methyl-5H,10H-benzo[b]1,6-naphthyridin-10-one CAS 157610-19-0 chemical structure

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.

6-methyl-5H,10H-benzo[b]1,6-naphthyridin-10-one (CAS 157610-19-0), molecular formula C13H10N2O and molecular weight 210.23 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 6-methyl-5H,10H-benzo[b]1,6-naphthyridin-10-one (C13H10N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 210.23 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
