7-Nitroindole-5-carboxylic acid methyl ester (CAS 1352398-33-4) is a high-purity analytical reference standard with the molecular formula C10H8N2O4 and a molecular weight of 220.18 g/mol.
7-Nitroindole-5-carboxylic acid methyl ester (C10H8N2O4) 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. 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.
