Ethionamide

Ethionamide Impurities & Reference Standards

Ethionamide is a high-purity active pharmaceutical ingredient (API) used in the formulation and manufacture of pharmaceutical products. Ethionamide is registered under CAS Number 536-33-4. With molecular formula C8H10N2S and molecular weight 166.2 g/mol, its physicochemical identity is well characterized. Analytical laboratories rely on Ethionamide and its associated impurity standards for method development, quality control testing, and pharmacopoeial compliance (ICH, USP, BP, EP). Our Ethionamide reference standards are provided with full documentation — Certificate of Analysis (CoA), HPLC chromatographic data, and spectral characterization — to support pharmaceutical R&D and GMP manufacturing.
