Chemical Structure
Description
2-methyl-2,7-diazaspiro[4.4]nonane dihydrochloride (CAS 91188-26-0), molecular formula C8H16N2HCl and molecular weight 176.69 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H16N2HCl, 2-methyl-2,7-diazaspiro[4.4]nonane dihydrochloride contains chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 176.69 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.
