21261-74-5 3-Chloro-N-(4-iodophenyl)propanamide MFCD01342247 (CAS 21261-74-5) is a high-purity analytical reference standard with the molecular formula C9H9ClINO and a molecular weight of 309.53 g/mol.
21261-74-5 3-Chloro-N-(4-iodophenyl)propanamide MFCD01342247 (C9H9ClINO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
