Chemical Structure
Description
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 supplies 2-Chloro-6-(4-methylpiperazin-1-yl)-9H-purine (CAS 121371-16-2), a certified reference material (molecular formula C10H13ClN6, MW 252.70 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2-Chloro-6-(4-methylpiperazin-1-yl)-9H-purine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 2-Chloro-6-(4-methylpiperazin-1-yl)-9H-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.
