Description
Compared with other compounds in its class, the molecular weight of 386.81 g/mol gives 3,12-Bis(2-chloroethyl)-3,12-diaza-6,9-diazoniadispiro[5.2.5.2]hexadecane dichloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3,12-Bis(2-chloroethyl)-3,12-diaza-6,9-diazoniadispiro[5.2.5.2]hexadecane dichloride (CAS 51657-49-9) is a high-purity analytical reference standard with the molecular formula C16H32Cl2N4Cl and a molecular weight of 386.81 g/mol.
3,12-Bis(2-chloroethyl)-3,12-diaza-6,9-diazoniadispiro[5.2.5.2]hexadecane dichloride (C16H32Cl2N4Cl) contains chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
