Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 373.23 g/mol gives 1-Methyl-2-(2-(naphthalen-1-yl)vinyl)pyridin-1-ium iodide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Methyl-2-(2-(naphthalen-1-yl)vinyl)pyridin-1-ium iodide (CAS 21915-05-9) is a high-purity analytical reference standard with the molecular formula C18H16NI and a molecular weight of 373.23 g/mol.
The molecular framework of 1-Methyl-2-(2-(naphthalen-1-yl)vinyl)pyridin-1-ium iodide (C18H16NI) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-Methyl-2-(2-(naphthalen-1-yl)vinyl)pyridin-1-ium iodide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
