Chemical Structure
Description
2-{2-[4-(trimethylsilyl)-1H-1,2,3-triazol-1-yl]ethyl}-2,3-dihydro-1H-isoindole-1,3-dione (CAS 1461706-40-0) is a high-purity analytical reference standard with the molecular formula C15H18N4O2Si and a molecular weight of 314.41 g/mol.
2-{2-[4-(trimethylsilyl)-1H-1,2,3-triazol-1-yl]ethyl}-2,3-dihydro-1H-isoindole-1,3-dione (C15H18N4O2Si) contains a nitrogen-containing heterocyclic scaffold, 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).
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.
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.
