Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(Cyclopentylamino)-2-(methylsulfanyl)pyrimidine-5-carbonitrile.
4-(Cyclopentylamino)-2-(methylsulfanyl)pyrimidine-5-carbonitrile (CAS 251372-07-3), molecular formula C11H14N4S and molecular weight 234.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(Cyclopentylamino)-2-(methylsulfanyl)pyrimidine-5-carbonitrile (C11H14N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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), 4-(Cyclopentylamino)-2-(methylsulfanyl)pyrimidine-5-carbonitrile 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.
