Resmetirom

Resmetirom Impurities

Resmetirom is a selective thyroid hormone receptor β (THR-β) agonist that is developed for the treatment of non-alcoholic steatohepatitis (NASH). Its impurity profile includes structurally related analogs, residual solvents, and degradation products. The impurities can be formed under stress conditions such as hydrolysis, oxidation, and photolysis. Typical degradation pathways involve oxidative breakdown of the heteroaromatic rings, hydrolytic cleavage of amide bonds, and rearrangement of substituents within the pyridazinone scaffold. These impurities may affect the potency, stability, and safety of the drug product . All impurities are structurally characterized and qualified according to ICH guidelines for toxicological assessment and analytical validation.

Resmetirom EP Impurities

We provide pharmacopeial and non-pharmacopeial Resmetirom impurity compounds that are available in compliance with European Pharmacopoeia (EP) specifications. These standards support analytical method development, impurity profiling, and long-term stability studies. EP traceable materials are supplied with validated analytical data, including purity, structural confirmation, and spectral characterization.

Resmetirom Related Compounds

Structurally related compounds and synthetic analogs of Resmetirom are included for impurity identification, toxicological qualification, and regulatory submission. These related substances are used in forced degradation studies, genotoxicity assessments, and impurity threshold evaluations. They are essential for understanding the impurity profile and ensuring compliance with regulatory limits.

Resmetirom Impurity Reference Standards

We provide Resmetirom impurity reference standards along with validated analytical data, including purity, NMR, MS, and full Certificates of Analysis. These standards are used in pharmaceutical research, method validation, and GMP-compliant quality control. EP/USP traceable entries are available upon request and are routinely re-tested to ensure consistency and reliability.
