Chemical Structure
Description
4-((9H-Fluoren-9-yl)methyl) 1-(tert-butyl) 2-hydroxypiperazine-1,4-dicarboxylate (C24H28N2O5) contains a flavonoid core, 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).
4-((9H-Fluoren-9-yl)methyl) 1-(tert-butyl) 2-hydroxypiperazine-1,4-dicarboxylate (CAS 1228675-21-5), molecular formula C24H28N2O5 and molecular weight 424.49 g/mol, is a CATO reference standard with documented purity and traceability.
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.
