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.
(Z)-N,N-Dibutyl-1-(octadec-9-en-1-yl)-5-oxopyrrolidine-3-carboxamide (CAS 93893-27-7), molecular formula C31H58N2O2 and molecular weight 490.80 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (Z)-N,N-Dibutyl-1-(octadec-9-en-1-yl)-5-oxopyrrolidine-3-carboxamide (C31H58N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 490.80 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.
