Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,13-Dioxa-4,7,10,16,19,22-hexaazacyclotetracosane Hexahydrochloride (CAS 126875-53-4), molecular formula C16H38N6O2HCl and molecular weight 382.98 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,13-Dioxa-4,7,10,16,19,22-hexaazacyclotetracosane Hexahydrochloride (C16H38N6O2HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
