Chemical Structure

Tert-butyl 3-fluoro-5-oxo-5,7-dihydrospiro[cyclopenta[b]pyridine-6,4'-piperidine]-1'-carboxylate CAS 2415987-68-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 320.36 g/mol gives Tert-butyl 3-fluoro-5-oxo-5,7-dihydrospiro[cyclopenta[b]pyridine-6,4'-piperidine]-1'-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tert-butyl 3-fluoro-5-oxo-5,7-dihydrospiro[cyclopenta[b]pyridine-6,4'-piperidine]-1'-carboxylate (CAS 2415987-68-5), molecular formula C17H21FN2O3 and molecular weight 320.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Tert-butyl 3-fluoro-5-oxo-5,7-dihydrospiro[cyclopenta[b]pyridine-6,4'-piperidine]-1'-carboxylate (C17H21FN2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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.

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.
