Chemical Structure

4-Ethylphenyl isocyanide CAS 143063-89-2 chemical structure

Description

As a certified reference material (CRM), 4-Ethylphenyl isocyanide 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.

4-Ethylphenyl isocyanide (CAS 143063-89-2) is a high-purity analytical reference standard with the molecular formula C9H9N and a molecular weight of 131.17 g/mol.

The molecular framework of 4-Ethylphenyl isocyanide (C9H9N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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