3,9-Diazaspiro[5.5]undec-3-yl(2-fluorophenyl)methanone hydrochloride CAS 1941105-08-3 chemical structure

Description

The occurrence of 3,9-Diazaspiro[5.5]undec-3-yl(2-fluorophenyl)methanone hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,9-Diazaspiro[5.5]undec-3-yl(2-fluorophenyl)methanone hydrochloride (CAS 1941105-08-3) is a high-purity analytical reference standard with the molecular formula C16H21FN2OHCl and a molecular weight of 312.81 g/mol.

Based on its molecular formula C16H21FN2OHCl, 3,9-Diazaspiro[5.5]undec-3-yl(2-fluorophenyl)methanone hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 312.81 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.
