Chemical Structure
Description
(2R,3S,5R)-5-(6-((2-Hydroxyethyl)amino)-9H-purin-9-yl)-2-(hydroxymethyl)tetrahydrofuran-3-ol (CAS 137058-94-7), molecular formula C12H17N5O4 and molecular weight 295.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (2R,3S,5R)-5-(6-((2-Hydroxyethyl)amino)-9H-purin-9-yl)-2-(hydroxymethyl)tetrahydrofuran-3-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (2R,3S,5R)-5-(6-((2-Hydroxyethyl)amino)-9H-purin-9-yl)-2-(hydroxymethyl)tetrahydrofuran-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.
