N1,N4-Bis(4-imino-2,5-cyclohexadien-1-ylidene)-1,4-benzenediamine CAS 137730-91-7

Description

Compared with other compounds in its class, the molecular weight of 286.33 g/mol gives N1,N4-Bis(4-imino-2,5-cyclohexadien-1-ylidene)-1,4-benzenediamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N1,N4-Bis(4-imino-2,5-cyclohexadien-1-ylidene)-1,4-benzenediamine (CAS 137730-91-7), molecular formula C18H14N4 and molecular weight 286.33 g/mol, is a CATO reference standard with documented purity and traceability.

N1,N4-Bis(4-imino-2,5-cyclohexadien-1-ylidene)-1,4-benzenediamine (C18H14N4) 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.

CATO manufactures N1,N4-Bis(4-imino-2,5-cyclohexadien-1-ylidene)-1,4-benzenediamine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
