1'-(tert-Butoxycarbonyl)-3,4-dihydro-2H-spiro[naphthalene-1,3'-pyrrolidine]-4'-carboxylic acid (CAS 1923056-76-1), molecular formula C19H25NO4 and molecular weight 331.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1'-(tert-Butoxycarbonyl)-3,4-dihydro-2H-spiro[naphthalene-1,3'-pyrrolidine]-4'-carboxylic acid (C19H25NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 331.41 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.
