Chemical Structure
Description
2-(3-Nitrophenyl)-1h-imidazole-4-carboxylic acid (CAS 601494-32-0) is a high-purity analytical reference standard with the molecular formula C10H7N3O4 and a molecular weight of 233.18 g/mol.
2-(3-Nitrophenyl)-1h-imidazole-4-carboxylic acid (C10H7N3O4) contains an amino-acid-derived structure, 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.
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.
