Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 2-(Ethylthio)-5-(4-phenylpiperazin-1-yl)-1,3,4-thiadiazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 306.45 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).
2-(Ethylthio)-5-(4-phenylpiperazin-1-yl)-1,3,4-thiadiazole (CAS 1105198-83-1), molecular formula C14H18N4S2 and molecular weight 306.45 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.
