Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 4-((4-(cyclopropanecarbonyl)-3-methyl-2-oxo-3,4-dihydroquinoxalin-1(2H)-yl)methyl)benzoate.
Methyl 4-((4-(cyclopropanecarbonyl)-3-methyl-2-oxo-3,4-dihydroquinoxalin-1(2H)-yl)methyl)benzoate (CAS 317833-57-1), molecular formula C22H22N2O4 and molecular weight 378.42 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Methyl 4-((4-(cyclopropanecarbonyl)-3-methyl-2-oxo-3,4-dihydroquinoxalin-1(2H)-yl)methyl)benzoate (C22H22N2O4) 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 378.42 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.
