1-(4-Methyl-3,4-dihydropyrido[2,3-b]pyrazin-1(2H)-yl)ethanone CAS 138768-66-8

Description

Based on its molecular formula C10H13N3O, 1-(4-Methyl-3,4-dihydropyrido[2,3-b]pyrazin-1(2H)-yl)ethanone contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 191.23 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).

1-(4-Methyl-3,4-dihydropyrido[2,3-b]pyrazin-1(2H)-yl)ethanone (CAS 138768-66-8), molecular formula C10H13N3O and molecular weight 191.23 g/mol, is a CATO reference standard with documented purity and traceability.

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.
