Description

Compared with other compounds in its class, the molecular weight of 291.37 g/mol gives Ethyl 2-amino-4-(4-methoxyphenyl)-5-methylthiophene-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 2-amino-4-(4-methoxyphenyl)-5-methylthiophene-3-carboxylate (CAS 350989-93-4) is a high-purity analytical reference standard with the molecular formula C15H17NO3S and a molecular weight of 291.37 g/mol.

The molecular framework of Ethyl 2-amino-4-(4-methoxyphenyl)-5-methylthiophene-3-carboxylate (C15H17NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
