2,2 inverted exclamation marka-[(1R,2R)-1,2-Cyclohexanediylbis[(E)-(nitrilomethylidyne)]]bis[4-(tert-butyl)-6-(1-piperidinylmethyl)phenol] 478282-28-9 N,N inverted exclamation marka-Bis[(E)-5-(tert-butyl)-2-hydroxy-3-(1-piperidinylmethyl)benzylidene]-[(1R,2R)-1,2-cyclohexanediamine] (C40H72N4O2) 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.
