Description
CATO supplies 6-Chloro-8-methyl-9-phenyl-9H-purine (CAS 70538-58-8), a certified reference material (molecular formula C12H9ClN4, MW 244.68 g/mol) for analytical method development and quality control.
Structurally, 6-Chloro-8-methyl-9-phenyl-9H-purine (C12H9ClN4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 244.68 g/mol, it falls into the medium-molecular-weight range. 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), 6-Chloro-8-methyl-9-phenyl-9H-purine 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.
