Chemical Structure
Description
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.
2-(Dicyclohexylamino)-2-oxoethyl 2-(4,4-dimethyl-2,5-dioxoimidazolidin-1-yl)acetate (CAS 731001-03-9), molecular formula C21H33N3O5 and molecular weight 407.50 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(Dicyclohexylamino)-2-oxoethyl 2-(4,4-dimethyl-2,5-dioxoimidazolidin-1-yl)acetate (C21H33N3O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 407.50 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
