Ethyl 2-amino-4-methyl-5-phenylthiophene-3-carboxylate CAS 4815-38-7

Description

Ethyl 2-amino-4-methyl-5-phenylthiophene-3-carboxylate (CAS 4815-38-7) is a high-purity analytical reference standard with the molecular formula C14H15NO2S and a molecular weight of 261.34 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 2-amino-4-methyl-5-phenylthiophene-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

As a certified reference material (CRM), Ethyl 2-amino-4-methyl-5-phenylthiophene-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
