Vigabatrin

Vigabatrin Impurities

Vigabatrin is an antiepileptic drug that acts as an irreversible inhibitor of GABA transaminase. Vigabatrin is generally used in the treatment of refractory epilepsy and infantile spasms. Its impurity profile includes structurally related analogs, residual solvents, and degradation products. These products can be formed under stress conditions such as hydrolysis, oxidation, and photolysis. Typical degradation pathways of Vigabatrin involve hydrolytic cleavage of amide bonds, oxidative breakdown of the vinyl group, and rearrangement of substituents within the pyrrolidine scaffold. 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.

Vigabatrin EP Impurities

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

Vigabatrin Related Compounds

Structurally related compounds and synthetic analogs of Vigabatrin 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. Therefore, these Vigabatrin related compounds are essential for understanding the impurity profile and ensuring compliance with regulatory limits.

Vigabatrin Impurity Reference Standards

We provide Vigabatrin impurity reference standards that are available 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. We also synthesize the EP/USP traceable impurities, which are available upon request and are routinely re-tested to ensure consistency and reliability.
