1,3-dimethyl 2-{3-[(ethoxycarbonyl)amino]-4-nitrophenyl}propanedioate CAS 1803598-22-2

Description

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.

1,3-dimethyl 2-{3-[(ethoxycarbonyl)amino]-4-nitrophenyl}propanedioate (CAS 1803598-22-2) is a high-purity analytical reference standard with the molecular formula C14H16N2O8 and a molecular weight of 340.29 g/mol.

1,3-dimethyl 2-{3-[(ethoxycarbonyl)amino]-4-nitrophenyl}propanedioate (C14H16N2O8) contains a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
