Chemical Structure
Description
3-(9-((4-Acetyl-3-hydroxy-2-propylphenoxy)methyl)-4-oxo-4H-pyrido[1,2-a]pyrimidin-3-yl)propanoic acid (CAS 112668-65-2), molecular formula C23H24N2O6 and molecular weight 424.45 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(9-((4-Acetyl-3-hydroxy-2-propylphenoxy)methyl)-4-oxo-4H-pyrido[1,2-a]pyrimidin-3-yl)propanoic acid (C23H24N2O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 424.45 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
