CATO supplies 1,4,8,11-Tetraazacyclotetrade cane-1,4,8,11-tetraacetic Acid HCl (CAS 78668-42-5), a certified reference material (molecular formula C18H32N4O8HClH2O, MW 486.95 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 1,4,8,11-Tetraazacyclotetrade cane-1,4,8,11-tetraacetic Acid HCl is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 486.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
