Chemical Structure
Description
4,4',4''-Triethyl-2,2':6',2''-terpyridine (CAS 33354-77-7), molecular formula C21H23N3 and molecular weight 317.43 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H23N3, 4,4',4''-Triethyl-2,2':6',2''-terpyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 317.43 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.
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 4,4',4''-Triethyl-2,2':6',2''-terpyridine 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.
