Description
Compared with other compounds in its class, the molecular weight of 212.68 g/mol gives 2-Chloro-N4-cyclopentylpyrimidine-4,5-diamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Chloro-N4-cyclopentylpyrimidine-4,5-diamine (CAS 893728-35-3), molecular formula C9H13ClN4 and molecular weight 212.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Chloro-N4-cyclopentylpyrimidine-4,5-diamine (C9H13ClN4) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Chloro-N4-cyclopentylpyrimidine-4,5-diamine 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.
