Chemical Structure
Description
As a certified reference material (CRM), 9-Butyl-6-(cyclopentylthio)-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.
CATO supplies 9-Butyl-6-(cyclopentylthio)-9H-purine (CAS 15923-49-6), a certified reference material (molecular formula C17H24O2, MW 260.37 g/mol) for analytical method development and quality control.
The molecular framework of 9-Butyl-6-(cyclopentylthio)-9H-purine (C17H24O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
