Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Chloro-N-cyclopentyl-2-(methylthio)pyrimidin-4-amine.
CATO supplies 6-Chloro-N-cyclopentyl-2-(methylthio)pyrimidin-4-amine (CAS 841260-74-0), a certified reference material (molecular formula C10H14ClN3S, MW 243.76 g/mol) for analytical method development and quality control.
Structurally, 6-Chloro-N-cyclopentyl-2-(methylthio)pyrimidin-4-amine (C10H14ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 243.76 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 6-Chloro-N-cyclopentyl-2-(methylthio)pyrimidin-4-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.
