Chemical Structure
Description
Ethyl 4-(4-(4-chlorophenyl)thiazol-2-yl)piperazine-1-carboxylate (CAS 346662-91-7) is a high-purity analytical reference standard with the molecular formula C16H18ClN3O2S and a molecular weight of 351.85 g/mol.
Based on its molecular formula C16H18ClN3O2S, Ethyl 4-(4-(4-chlorophenyl)thiazol-2-yl)piperazine-1-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 351.85 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
