Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[[4-(Acetyloxy)-3,5-diiodophenyl]methylene]-2-methyl-5(4H)-oxazolone (E/Z Mixture).
CATO supplies 4-[[4-(Acetyloxy)-3,5-diiodophenyl]methylene]-2-methyl-5(4H)-oxazolone (E/Z Mixture) (CAS 93087-37-7), a certified reference material (molecular formula C13H9I2NO4, MW 497.02 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution, 4-[[4-(Acetyloxy)-3,5-diiodophenyl]methylene]-2-methyl-5(4H)-oxazolone (E/Z Mixture) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 497.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
