Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Iodo-6-methylpyrimidine-2,4-diol (CAS 1461-67-2), molecular formula C5H5IN2O2 and molecular weight 252.01 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, 5-Iodo-6-methylpyrimidine-2,4-diol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.01 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), 5-Iodo-6-methylpyrimidine-2,4-diol 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.
