Chemical Structure

4-(4-diethylaminostyryl)-1-methylpyridinium iodide CAS 105802-46-8 chemical structure

Description

The molecular framework of 4-(4-diethylaminostyryl)-1-methylpyridinium iodide (C18H34N2I) is characterized by a nitrile group, iodine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

4-(4-diethylaminostyryl)-1-methylpyridinium iodide (CAS 105802-46-8) is a high-purity analytical reference standard with the molecular formula C18H34N2I and a molecular weight of 405.38 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), 4-(4-diethylaminostyryl)-1-methylpyridinium iodide 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.
