Chemical Structure
Description
3-Allyl-2-chloro-4-iodopyridine (CAS 1142192-13-9) is a high-purity analytical reference standard with the molecular formula C8H7ClIN and a molecular weight of 279.51 g/mol.
The molecular framework of 3-Allyl-2-chloro-4-iodopyridine (C8H7ClIN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 3-Allyl-2-chloro-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.
