Description
Compared with other compounds in its class, the molecular weight of 239.29 g/mol gives Ethyl 2-[3-(methylthio)anilino]-2-oxoacetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-[3-(methylthio)anilino]-2-oxoacetate (CAS 63170-23-0), molecular formula C11H13NO3S and molecular weight 239.29 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Ethyl 2-[3-(methylthio)anilino]-2-oxoacetate (C11H13NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 239.29 g/mol, it falls into the medium-molecular-weight range. 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).
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.
