4-(6-Methoxypyridin-2-yl)benzaldehyde CAS 618092-16-3

Description

The occurrence of 4-(6-Methoxypyridin-2-yl)benzaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(6-Methoxypyridin-2-yl)benzaldehyde (CAS 618092-16-3), molecular formula C13H11NO2 and molecular weight 213.23 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-(6-Methoxypyridin-2-yl)benzaldehyde (C13H11NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 213.23 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
