Chemical Structure

Ethyl 2-amino-4-(4-butylphenyl)thiophene-3-carboxylate CAS 350990-06-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-amino-4-(4-butylphenyl)thiophene-3-carboxylate.

Ethyl 2-amino-4-(4-butylphenyl)thiophene-3-carboxylate (CAS 350990-06-6) is a high-purity analytical reference standard with the molecular formula C17H21NO2S and a molecular weight of 303.42 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 2-amino-4-(4-butylphenyl)thiophene-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
