4,4',4''-((Benzene-1,3,5-tricarbonyl)tris(azanediyl))tribenzoic acid CAS 120360-51-2

Description

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.

4,4',4''-((Benzene-1,3,5-tricarbonyl)tris(azanediyl))tribenzoic acid (CAS 120360-51-2), molecular formula C30H21N3O9 and molecular weight 567.50 g/mol, is a CATO reference standard with documented purity and traceability.

4,4',4''-((Benzene-1,3,5-tricarbonyl)tris(azanediyl))tribenzoic acid (C30H21N3O9) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
