Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
5-chloro-4-iodo-1,2-dihydropyridin-2-one (CAS 1125410-07-2) is a high-purity analytical reference standard with the molecular formula C5H7ClINO and a molecular weight of 259.47 g/mol.
The molecular framework of 5-chloro-4-iodo-1,2-dihydropyridin-2-one (C5H7ClINO) is characterized by an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 5-chloro-4-iodo-1,2-dihydropyridin-2-one 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.
