Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Methoxypyridin-4(1H)-one.
3-Methoxypyridin-4(1H)-one (CAS 50700-60-2) is a high-purity analytical reference standard with the molecular formula C11H23NSHCl and a molecular weight of 237.83 g/mol.
Owing to sulfur-containing functionality, chlorine substitution, 3-Methoxypyridin-4(1H)-one is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 237.83 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.
