Chemical Structure
Description
2',3',5',6'-Tetramethyl-4,4''-dinitro-1,1':4',1''-terphenyl (C22H24N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
2',3',5',6'-Tetramethyl-4,4''-dinitro-1,1':4',1''-terphenyl (CAS 444017-79-2), molecular formula C22H24N2 and molecular weight 316.44 g/mol, is a CATO reference standard with documented purity and traceability.
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.
