Chemical Structure
Description
The occurrence of 5-Chloro-8-iodoquinoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Chloro-8-iodoquinoline (CAS 859958-87-5), a certified reference material (molecular formula C9H5ClIN, MW 289.50 g/mol) for analytical method development and quality control.
5-Chloro-8-iodoquinoline (C9H5ClIN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 5-Chloro-8-iodoquinoline 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.
