Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Ethyl-2-(4-methylstyryl)quinolin-1-ium iodide.
1-Ethyl-2-(4-methylstyryl)quinolin-1-ium iodide (CAS 50496-72-5), molecular formula C20H20NI and molecular weight 401.29 g/mol, is a CATO reference standard with documented purity and traceability.
1-Ethyl-2-(4-methylstyryl)quinolin-1-ium iodide (C20H20NI) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine 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. 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-Ethyl-2-(4-methylstyryl)quinolin-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.
