Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 289.50 g/mol gives 5-Chloro-7-iodoquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Chloro-7-iodoquinoline (CAS 30535-26-3), molecular formula C9H5ClIN and molecular weight 289.50 g/mol, is a CATO reference standard with documented purity and traceability.
5-Chloro-7-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.
As a certified reference material (CRM), 5-Chloro-7-iodoquinoline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
