8-Methyl-1,7-naphthyridine CAS 90685-65-7

Description

The occurrence of 8-Methyl-1,7-naphthyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 8-Methyl-1,7-naphthyridine (CAS 90685-65-7), a certified reference material (molecular formula C9H8N2, MW 144.17 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 8-Methyl-1,7-naphthyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
