Chemical Structure

1'-tert-Butyl 4'-ethyl 3,4-dihydro-2H-spiro[naphthalene-1,3'-pyrrolidine]-1',4'-dicarboxylate CAS 1956382-64-1 chemical structure

Description

The occurrence of 1'-tert-Butyl 4'-ethyl 3,4-dihydro-2H-spiro[naphthalene-1,3'-pyrrolidine]-1',4'-dicarboxylate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1'-tert-Butyl 4'-ethyl 3,4-dihydro-2H-spiro[naphthalene-1,3'-pyrrolidine]-1',4'-dicarboxylate (CAS 1956382-64-1) is a high-purity analytical reference standard with the molecular formula C21H29NO4 and a molecular weight of 359.46 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 1'-tert-Butyl 4'-ethyl 3,4-dihydro-2H-spiro[naphthalene-1,3'-pyrrolidine]-1',4'-dicarboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 359.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
