Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-iodo-3-methyl-1,2,4-oxadiazole.
5-iodo-3-methyl-1,2,4-oxadiazole (CAS 88947-63-1), molecular formula C3H7IN2O and molecular weight 214.00 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, iodine substitution, 5-iodo-3-methyl-1,2,4-oxadiazole is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.00 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.
As a certified reference material (CRM), 5-iodo-3-methyl-1,2,4-oxadiazole 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.
