Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N2,N3,1,4-tetraphenylbutane-2,3-diamine.
N2,N3,1,4-tetraphenylbutane-2,3-diamine (CAS 126503-85-3) is a high-purity analytical reference standard with the molecular formula C28H28N2 and a molecular weight of 392.54 g/mol.
N2,N3,1,4-tetraphenylbutane-2,3-diamine (C28H28N2) 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.
As a certified reference material (CRM), N2,N3,1,4-tetraphenylbutane-2,3-diamine 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.
