Chemical Structure
Description
As a certified reference material (CRM), 2,6-Dichloro-4-iodophenol 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.
2,6-Dichloro-4-iodophenol (CAS 34074-22-1), molecular formula C6H3Cl2IO and molecular weight 288.90 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system, 2,6-Dichloro-4-iodophenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
