22509-74-6 DGO9NPX8LS N-Carbethoxyphthalimide Ethyl 1,3-dihydro-1,3-dioxo-2H-isoindole-2-carboxylate 2H-Isoindole-2-carboxylic acid, 1,3-dihydro-1,3-dioxo-, ethyl ester 2-Isoindolinecarboxylic acid, 1,3-dioxo-, ethyl ester 5-21-10-00428 (Beilstein Handbook Reference) AI3-52139 BRN 0196340 N-Carboethoxyphthalimide EINECS 245-048-5 N-(Ethoxycarbonyl)phthalimide Ethyl N-phthaloylcarbamate N-Karbetoksi-ftalimid [Yugoslavian] NSC 76576 Phthalimide-N-carbethoxy N-Karbetoksi-ftalimid UNII-DGO9NPX8LS (C11H15NO4) 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.
