(E)-[1-(2,4-Dimethyl-1,3-thiazol-5-yl)ethylidene]amino 3,4-dichlorobenzoate (CAS 477872-40-5), molecular formula C14H12Cl2N2O2S and molecular weight 343.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-[1-(2,4-Dimethyl-1,3-thiazol-5-yl)ethylidene]amino 3,4-dichlorobenzoate (C14H12Cl2N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
