2,5-Dioxopyrrolidin-1-yl (2-(trimethylsilyl)ethyl) carbonate 1-[2-(Trimethylsilyl)ethoxycarbonyloxy]pyrrolidin-2,5-dione 78269-85-9 (CAS 78269-85-9), molecular formula C10H17NO5Si and molecular weight 259.33 g/mol, is a CATO reference standard with documented purity and traceability.
2,5-Dioxopyrrolidin-1-yl (2-(trimethylsilyl)ethyl) carbonate 1-[2-(Trimethylsilyl)ethoxycarbonyloxy]pyrrolidin-2,5-dione 78269-85-9 (C10H17NO5Si) 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.
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.
