Chemical Structure
Description
6-Chloro-2-cyclopentyl-7-methyl-7H-purine (CAS 1708178-71-5) is a high-purity analytical reference standard with the molecular formula C11H13ClN4 and a molecular weight of 236.70 g/mol.
Based on its molecular formula C11H13ClN4, 6-Chloro-2-cyclopentyl-7-methyl-7H-purine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 6-Chloro-2-cyclopentyl-7-methyl-7H-purine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
