Lifitegrast is a lymphocyte function-associated antigen-1 (LFA-1) antagonist that is generally used in the treatment of dry eye disease. Its impurity profile includes structurally related analogs, residual solvents, and degradation products. These impurities may form under stress conditions such as hydrolysis, oxidation, and photolysis. Typical degradation pathways of Lifitegrast API involve oxidative breakdown of the phenylalanine-derived moieties, hydrolytic cleavage of amide bonds, and rearrangement of heteroaromatic substituents. These impurities may affect the potency, stability, and safety of the drug. Hence, all impurities are structurally characterized and qualified according to ICH guidelines for toxicological assessment and analytical validation.
We provide pharmacopeial and non-pharmacopeial Lifitegrast 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.
Structurally related compounds and synthetic analogs of Lifitegrast 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.
We provide Lifitegrast impurity reference standards 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.
