Chemical Structure

2-Acetylpyridine N-oxide CAS 2457-50-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 137.14 g/mol gives 2-Acetylpyridine N-oxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Acetylpyridine N-oxide (CAS 2457-50-3), molecular formula C7H7NO2 and molecular weight 137.14 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H7NO2, 2-Acetylpyridine N-oxide contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 137.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
