Chemical Structure
Description
2-(2-Hydroxyethyl)-5-nitroisoindoline-1,3-dione (CAS 55080-96-1), molecular formula C10H8N2O5 and molecular weight 236.18 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2-Hydroxyethyl)-5-nitroisoindoline-1,3-dione (C10H8N2O5) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
