Chemical Structure
Description
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.
Carbamic acid,n-[[4-(2,4-dichlorophenyl)-6-[2-(dimethylamino)-2-oxoethyl]-6,7-dihydro-2-methyl-5-oxo-5H-pyrrolo[3,4-b]pyridin-3-yl]methyl]-,1,1-dimethylethylester (CAS 915731-88-3), molecular formula C24H28Cl2N4O4 and molecular weight 507.41 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Carbamic acid,n-[[4-(2,4-dichlorophenyl)-6-[2-(dimethylamino)-2-oxoethyl]-6,7-dihydro-2-methyl-5-oxo-5H-pyrrolo[3,4-b]pyridin-3-yl]methyl]-,1,1-dimethylethylester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 507.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
