Chemical Structure
Description
As a certified reference material (CRM), 2,6-Diiodopyridin-3-ol 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-Diiodopyridin-3-ol (CAS 14764-90-0), molecular formula C5H3I2NO and molecular weight 346.89 g/mol, is a CATO reference standard with documented purity and traceability.
2,6-Diiodopyridin-3-ol (C5H3I2NO) contains an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
