Chemical Structure
Description
2-Chloro-5-fluoro-4-iodopyridine (CAS 884494-49-9), molecular formula C5H2ClFIN and molecular weight 257.43 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Chloro-5-fluoro-4-iodopyridine (C5H2ClFIN) contains a nitrile group, fluorine/chlorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 257.43 g/mol, it falls into the medium-molecular-weight range. 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).
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-Chloro-5-fluoro-4-iodopyridine 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.
