Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Chloro-N-cyclohexyl-9-methyl-9H-purin-6-amine.
2-Chloro-N-cyclohexyl-9-methyl-9H-purin-6-amine (CAS 925254-29-1), molecular formula C12H16ClN5 and molecular weight 265.74 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-N-cyclohexyl-9-methyl-9H-purin-6-amine (C12H16ClN5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 2-Chloro-N-cyclohexyl-9-methyl-9H-purin-6-amine 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.
