5-iodo-3,7-dihydropyrrolo[2,3-d]pyrimidin-4-one (CAS 135352-71-5) is a high-purity analytical reference standard with the molecular formula C6H10IN3O and a molecular weight of 267.07 g/mol.
The molecular framework of 5-iodo-3,7-dihydropyrrolo[2,3-d]pyrimidin-4-one (C6H10IN3O) is characterized by an amide group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 5-iodo-3,7-dihydropyrrolo[2,3-d]pyrimidin-4-one 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.
