Description
CATO supplies 4,4',4'',4'''-((1,4,8,11-Tetraazacyclotetradecane-1,4,8,11-tetrayl)tetrakis(methylene))tetrabenzoic acid (CAS 1886010-85-0), a certified reference material (molecular formula C42H48N4O8, MW 736.85 g/mol) for analytical method development and quality control.
4,4',4'',4'''-((1,4,8,11-Tetraazacyclotetradecane-1,4,8,11-tetrayl)tetrakis(methylene))tetrabenzoic acid (C42H48N4O8) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
