Exatecan

About Exatecan

Exatecan is a stable isotope labelled analogue related to Camptothecin carrying the CAS registry number 171335-80-1. The compound has the formula C24H22FN3O4, corresponding to a molecular weight of 435.4 g/mol. Common synonyms include exatecan-mesylate and Exatecan free base.

The product is provided as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. It carries the GHS signal word “Danger” with 2 hazard statements. Review the Safety Data Sheet before use.

Its mass shift relative to the unlabelled analyte makes it a dependable internal standard for LC-MS/MS assays, improving accuracy in bioanalysis, therapeutic drug monitoring and method validation. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, Exatecan is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
