Chemical Structure
Description
As a certified reference material (CRM), 2-Iodo-6-Chloropurine 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 2-Iodo-6-Chloropurine (CAS 18552-90-4), a certified reference material (molecular formula C5H2ClIN4, MW 280.45 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine/iodine substitution, 2-Iodo-6-Chloropurine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.45 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
