Irinotecan

Irinotecan Impurities

Irinotecan is a semisynthetic derivative of camptothecin that is generally used as a topoisomerase I inhibitor in the treatment of colorectal and other solid tumors. The impurity profile of the drug product includes structurally related analogs, residual solvents, and degradation products. These pharmaceutical impurities can be formed under stress conditions such as hydrolysis, oxidation, and photolysis. Typical degradation pathways of Irinotecan may involve hydrolytic cleavage of the carbamate group, oxidative breakdown of the camptothecin core, and rearrangement of substituents within the lactone ring. These impurities may affect the potency, stability, and safety of the drug. Thus, all impurities related to Irinotecan must be structurally characterized and qualified according to ICH guidelines for toxicological assessment and analytical validation.

Irinotecan EP Impurities

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

Irinotecan Related Compounds

Structurally related compounds and synthetic analogs of Irinotecan 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.

Irinotecan Impurity Reference Standards

We also provide the Irinotecan 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. EP/USP traceable entries are available upon request and are routinely re-tested to ensure consistency and reliability.
