As a certified reference material (CRM), 2,8-dichloro-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.
2,8-dichloro-9H-purine (CAS 89166-91-6), molecular formula C5H10Cl2N4 and molecular weight 197.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,8-dichloro-9H-purine (C5H10Cl2N4) is characterized by a nitrile group, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
