Chemical Structure
Description
2,4'-Bipyridyl (CAS 581-47-5) is a high-purity analytical reference standard with the molecular formula C10H8N2 and a molecular weight of 156.18 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2,4'-Bipyridyl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2,4'-Bipyridyl 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.
