Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 553.43 g/mol gives O-Isobutyryl N-methyl naltrexone iodide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
O-Isobutyryl N-methyl naltrexone iodide (CAS 1048360-09-3) is a high-purity analytical reference standard with the molecular formula C25H32NO5I and a molecular weight of 553.43 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, O-Isobutyryl N-methyl naltrexone iodide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 553.43 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), O-Isobutyryl N-methyl naltrexone iodide 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.
