4,4',4",4"'-(Pyrene-1,3,6,8-tetrayl)tetrakis(3-aminobenzoic acid) CAS 2225892-57-7

Description

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.

4,4',4",4"'-(Pyrene-1,3,6,8-tetrayl)tetrakis(3-aminobenzoic acid) (CAS 2225892-57-7) is a high-purity analytical reference standard with the molecular formula C44H30N4O8 and a molecular weight of 742.73 g/mol.

4,4',4",4"'-(Pyrene-1,3,6,8-tetrayl)tetrakis(3-aminobenzoic acid) (C44H30N4O8) 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).

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.
