Tert-butyl 4,4-difluoro-1,7-diazaspiro[4.4]Nonane-7-carboxylate CAS 1889110-75-1

Description

The occurrence of Tert-butyl 4,4-difluoro-1,7-diazaspiro[4.4]Nonane-7-carboxylate is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Tert-butyl 4,4-difluoro-1,7-diazaspiro[4.4]Nonane-7-carboxylate (CAS 1889110-75-1), a certified reference material (molecular formula C12H20F2N2O2, MW 262.30 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H20F2N2O2, Tert-butyl 4,4-difluoro-1,7-diazaspiro[4.4]Nonane-7-carboxylate contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 262.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
