(2E)-3-[2-(2,4-Dichlorophenoxy)phenyl]-2-{4-[2-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)ethyl]-1,3-thiazol-2-yl}prop-2-enenitrile (CAS 866019-87-6), molecular formula C28H17Cl2N3O3S and molecular weight 546.42 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, (2E)-3-[2-(2,4-Dichlorophenoxy)phenyl]-2-{4-[2-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)ethyl]-1,3-thiazol-2-yl}prop-2-enenitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 546.42 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.
