Chemical Structure
Description
As a certified reference material (CRM), 3-(Difluoromethyl)-4-iodopyridine 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.
3-(Difluoromethyl)-4-iodopyridine (CAS 1805958-34-2) is a high-purity analytical reference standard with the molecular formula C6H4F2IN and a molecular weight of 255.00 g/mol.
3-(Difluoromethyl)-4-iodopyridine (C6H4F2IN) contains a nitrile group, fluorine/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.
