Description
As a certified reference material (CRM), 8-Chloro-7-iodoimidazo[1,2-a]pyridine 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.
8-Chloro-7-iodoimidazo[1,2-a]pyridine (CAS 1447607-66-0) is a high-purity analytical reference standard with the molecular formula C7H4ClIN2 and a molecular weight of 278.48 g/mol.
8-Chloro-7-iodoimidazo[1,2-a]pyridine (C7H4ClIN2) contains a nitrile group, chlorine/iodine substitution, an aromatic ring system. 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.
