Chemical Structure

4-Butyl-N-(4-(tert-butyl)phenyl)aniline CAS 398483-80-2 chemical structure

Description

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.

4-Butyl-N-(4-(tert-butyl)phenyl)aniline (CAS 398483-80-2), molecular formula C20H27N and molecular weight 281.44 g/mol, is a CATO reference standard with documented purity and traceability.

4-Butyl-N-(4-(tert-butyl)phenyl)aniline (C20H27N) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), 4-Butyl-N-(4-(tert-butyl)phenyl)aniline 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.
