Chemical Structure

1,3,5,9-Tetraazaspiro[5.5]undecane CAS 353799-75-4 chemical structure

Description

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.

1,3,5,9-Tetraazaspiro[5.5]undecane (CAS 353799-75-4), molecular formula C7H16N4 and molecular weight 156.23 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H16N4, 1,3,5,9-Tetraazaspiro[5.5]undecane contains a nitrile group; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 156.23 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.

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.
