Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(5-Amino-1,3-dioxoisoindolin-2-yl)acetic acid (CAS 10133-85-4) is a high-purity analytical reference standard with the molecular formula C10H8N2O4 and a molecular weight of 220.18 g/mol.
2-(5-Amino-1,3-dioxoisoindolin-2-yl)acetic acid (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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
