1'-(tert-Butoxycarbonyl)-5,6-dihydro-4H-spiro[benzo[b]thiophene-7,4'-piperidine]-2-carboxylic acid CAS 1624261-80-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1'-(tert-Butoxycarbonyl)-5,6-dihydro-4H-spiro[benzo[b]thiophene-7,4'-piperidine]-2-carboxylic acid.

1'-(tert-Butoxycarbonyl)-5,6-dihydro-4H-spiro[benzo[b]thiophene-7,4'-piperidine]-2-carboxylic acid (CAS 1624261-80-8) is a high-purity analytical reference standard with the molecular formula C18H25NO4S and a molecular weight of 351.46 g/mol.

Based on its molecular formula C18H25NO4S, 1'-(tert-Butoxycarbonyl)-5,6-dihydro-4H-spiro[benzo[b]thiophene-7,4'-piperidine]-2-carboxylic acid contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 351.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
