Description
As a certified reference material (CRM), 7-Iodo-1,3-dihydroisobenzofuran-4-amine 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.
7-Iodo-1,3-dihydroisobenzofuran-4-amine (CAS 2764887-67-2), molecular formula C8H8INO and molecular weight 261.06 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C8H8INO, 7-Iodo-1,3-dihydroisobenzofuran-4-amine contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 261.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
