Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, 5,7-Dihydro-4H-purin-6-ol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.13 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).
5,7-Dihydro-4H-purin-6-ol (CAS 98325-50-9), molecular formula C5H6N4O and molecular weight 138.13 g/mol, is a CATO reference standard with documented purity and traceability.
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), 5,7-Dihydro-4H-purin-6-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.
