Ethyl 3-amino-5-(tert-butyl)thiophene-2-carboxylate CAS 439693-51-3

Description

The occurrence of Ethyl 3-amino-5-(tert-butyl)thiophene-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.

Ethyl 3-amino-5-(tert-butyl)thiophene-2-carboxylate (CAS 439693-51-3) is a high-purity analytical reference standard with the molecular formula C11H17NO2S and a molecular weight of 227.32 g/mol.

The molecular framework of Ethyl 3-amino-5-(tert-butyl)thiophene-2-carboxylate (C11H17NO2S) 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.
