4-Fluoro-2-methoxynicotinaldehyde CAS 1932259-66-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Fluoro-2-methoxynicotinaldehyde.

4-Fluoro-2-methoxynicotinaldehyde (CAS 1932259-66-9), molecular formula C7H6FNO2 and molecular weight 155.13 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H6FNO2, 4-Fluoro-2-methoxynicotinaldehyde contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 155.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
