Chemical Structure
Description
1-Hexyl-2-(4-(methylthio)styryl)pyridin-1-ium iodide (CAS 307952-95-0), molecular formula C20H26NSI and molecular weight 439.39 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H26NSI, 1-Hexyl-2-(4-(methylthio)styryl)pyridin-1-ium iodide contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 439.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1-Hexyl-2-(4-(methylthio)styryl)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.
