Chemical Structure

N,N''-Bis(methylphenyl)-1,4-benzenediamine CAS 27417-40-9 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, N,N''-Bis(methylphenyl)-1,4-benzenediamine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

N,N''-Bis(methylphenyl)-1,4-benzenediamine (CAS 27417-40-9) is a high-purity analytical reference standard with the molecular formula C20H20N2 and a molecular weight of 288.39 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), N,N''-Bis(methylphenyl)-1,4-benzenediamine 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.
