Chemical Structure

1,4-Benzenediamine, N1,N4-bis(1-methylethyl)- CAS 4251-01-8 chemical structure

Description

The molecular framework of 1,4-Benzenediamine, N1,N4-bis(1-methylethyl)- (C12H20N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

1,4-Benzenediamine, N1,N4-bis(1-methylethyl)- (CAS 4251-01-8) is a high-purity analytical reference standard with the molecular formula C12H20N2 and a molecular weight of 192.30 g/mol.

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), 1,4-Benzenediamine, N1,N4-bis(1-methylethyl)- 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.
