tert-Butyl 3-methyl-4-[(quinolin-3-yl)methyl]piperazine-1-carboxylate (CAS 1798518-88-3), molecular formula C20H27N3O2 and molecular weight 341.45 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, tert-Butyl 3-methyl-4-[(quinolin-3-yl)methyl]piperazine-1-carboxylate (C20H27N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 341.45 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.
