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.
4-(5-CYANO-1,3-DIOXO-1H-BENZO[DE]ISOQUINOLIN-2(3H)-YL)BUTANOIC ACID (CAS 929519-89-1) is a high-purity analytical reference standard with the molecular formula C17H12N2O4 and a molecular weight of 308.29 g/mol.
4-(5-CYANO-1,3-DIOXO-1H-BENZO[DE]ISOQUINOLIN-2(3H)-YL)BUTANOIC ACID (C17H12N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
