Chemical Structure

1'-Benzyl 6-ethyl spiro[indoline-3,4'-piperidine]-1',6-dicarboxylate CAS 1243347-00-3 chemical structure

Description

The occurrence of 1'-Benzyl 6-ethyl spiro[indoline-3,4'-piperidine]-1',6-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'-Benzyl 6-ethyl spiro[indoline-3,4'-piperidine]-1',6-dicarboxylate (CAS 1243347-00-3) is a high-purity analytical reference standard with the molecular formula C23H26N2O4 and a molecular weight of 394.46 g/mol.

The molecular framework of 1'-Benzyl 6-ethyl spiro[indoline-3,4'-piperidine]-1',6-dicarboxylate (C23H26N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 1'-Benzyl 6-ethyl spiro[indoline-3,4'-piperidine]-1',6-dicarboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
