Chemical Structure
Description
5-(6-Amino-9H-purin-9-yl)-3-methylcyclopent-3-ene-1,2-diol (CAS 5261-79-0), molecular formula C11H13N5O2 and molecular weight 247.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(6-Amino-9H-purin-9-yl)-3-methylcyclopent-3-ene-1,2-diol (C11H13N5O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. 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.
As a certified reference material (CRM), 5-(6-Amino-9H-purin-9-yl)-3-methylcyclopent-3-ene-1,2-diol 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.
