The occurrence of (2S,3S,4R,5R)-3,4-Dihydroxy-5-[6-(3-iodobenzylamino)-9H-purin-9-yl]-N-methyltetrahydrofuran-2-carboxamide is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2S,3S,4R,5R)-3,4-Dihydroxy-5-[6-(3-iodobenzylamino)-9H-purin-9-yl]-N-methyltetrahydrofuran-2-carboxamide (CAS 152918-18-8), molecular formula C18H19IN6O4 and molecular weight 510.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2S,3S,4R,5R)-3,4-Dihydroxy-5-[6-(3-iodobenzylamino)-9H-purin-9-yl]-N-methyltetrahydrofuran-2-carboxamide (C18H19IN6O4) is characterized by a flavonoid core, 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. 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.
As a certified reference material (CRM), (2S,3S,4R,5R)-3,4-Dihydroxy-5-[6-(3-iodobenzylamino)-9H-purin-9-yl]-N-methyltetrahydrofuran-2-carboxamide 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.
