Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 206.67 g/mol gives 1-(4-Aminophenyl)pyridin-1-ium chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-(4-Aminophenyl)pyridin-1-ium chloride (CAS 78427-26-6), a certified reference material (molecular formula C11H11N2Cl, MW 206.67 g/mol) for analytical method development and quality control.
1-(4-Aminophenyl)pyridin-1-ium chloride (C11H11N2Cl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(4-Aminophenyl)pyridin-1-ium chloride 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.
