Chemical Structure
Description
The molecular framework of (E)-N-{5-[(1E)-1-cyano-2-(4-methoxyphenyl)eth-1-en-1-yl]-1,3,4-thiadiazol-2-yl}-N'-methoxymethanimidamide (C14H13N5O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
(E)-N-{5-[(1E)-1-cyano-2-(4-methoxyphenyl)eth-1-en-1-yl]-1,3,4-thiadiazol-2-yl}-N'-methoxymethanimidamide (CAS 338775-61-4), molecular formula C14H13N5O2S and molecular weight 315.35 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
