4-iodo-1,2-dihydro-2,7-naphthyridin-1-one CAS 959558-50-0

Description

The occurrence of 4-iodo-1,2-dihydro-2,7-naphthyridin-1-one is closely related to an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-iodo-1,2-dihydro-2,7-naphthyridin-1-one (CAS 959558-50-0), molecular formula C8H13IN2O and molecular weight 280.11 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, iodine substitution, 4-iodo-1,2-dihydro-2,7-naphthyridin-1-one is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
