Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-((2,2-diphenylhydrazono)methyl)-N,N-di-p-tolylaniline.
(E)-4-((2,2-diphenylhydrazono)methyl)-N,N-di-p-tolylaniline (CAS 906674-39-3), molecular formula C33H29N3 and molecular weight 467.60 g/mol, is a CATO reference standard with documented purity and traceability.
(E)-4-((2,2-diphenylhydrazono)methyl)-N,N-di-p-tolylaniline (C33H29N3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
