Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Chloro-3-ethylpyridine (CAS 860411-22-9), molecular formula C7H8ClN and molecular weight 141.60 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine substitution, an aromatic ring system, 4-Chloro-3-ethylpyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 4-Chloro-3-ethylpyridine 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.
