Chemical Structure

(E)-N,N-diethyl-4-(pyridin-4-yldiazenyl)aniline CAS 89762-42-5 chemical structure

Description

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

(E)-N,N-diethyl-4-(pyridin-4-yldiazenyl)aniline (CAS 89762-42-5) is a high-purity analytical reference standard with the molecular formula C15H18N4 and a molecular weight of 254.33 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, (E)-N,N-diethyl-4-(pyridin-4-yldiazenyl)aniline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 254.33 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.

As a certified reference material (CRM), (E)-N,N-diethyl-4-(pyridin-4-yldiazenyl)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.
