Chemical Structure
Description
N-(4-Ethoxybenzo[d]thiazol-2-yl)acetamide (CAS 313661-90-4), molecular formula C11H12N2O2S and molecular weight 236.29 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H12N2O2S, N-(4-Ethoxybenzo[d]thiazol-2-yl)acetamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
