2-Oxo-2-(p-tolylamino)ethyl 5-methylthiophene-2-carboxylate CAS 387855-01-8

Description

The occurrence of 2-Oxo-2-(p-tolylamino)ethyl 5-methylthiophene-2-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Oxo-2-(p-tolylamino)ethyl 5-methylthiophene-2-carboxylate (CAS 387855-01-8) is a high-purity analytical reference standard with the molecular formula C15H15NO3S and a molecular weight of 289.35 g/mol.

Based on its molecular formula C15H15NO3S, 2-Oxo-2-(p-tolylamino)ethyl 5-methylthiophene-2-carboxylate 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 289.35 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
