Chemical Structure
Description
The occurrence of 3,5-Bis(3-iodo-4-methoxyphenethyl)isoxazole is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,5-Bis(3-iodo-4-methoxyphenethyl)isoxazole (CAS 88551-74-0), a certified reference material (molecular formula C21H21I2NO3, MW 589.21 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, 3,5-Bis(3-iodo-4-methoxyphenethyl)isoxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 589.21 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), 3,5-Bis(3-iodo-4-methoxyphenethyl)isoxazole 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.
