The occurrence of 5,5',5''-(((2,4,6-Trimethylbenzene-1,3,5-triyl)tris(methylene))tris(oxy))triisophthalic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5,5',5''-(((2,4,6-Trimethylbenzene-1,3,5-triyl)tris(methylene))tris(oxy))triisophthalic acid (CAS 1159974-70-5), molecular formula C36H30O15 and molecular weight 702.61 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 5,5',5''-(((2,4,6-Trimethylbenzene-1,3,5-triyl)tris(methylene))tris(oxy))triisophthalic acid is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 702.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 5,5',5''-(((2,4,6-Trimethylbenzene-1,3,5-triyl)tris(methylene))tris(oxy))triisophthalic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
