Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-chloro-9-(1-methyl-1H-pyrazol-4-yl)-9H-purine (CAS 2386703-96-2) is a high-purity analytical reference standard with the molecular formula C9H7ClN6 and a molecular weight of 234.65 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2-chloro-9-(1-methyl-1H-pyrazol-4-yl)-9H-purine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.65 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.
As a certified reference material (CRM), 2-chloro-9-(1-methyl-1H-pyrazol-4-yl)-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.
