About Closantel

Closantel (CAS 57808-65-8) is a high-purity reference standard of Closantel offered by Vaqora Chemicals. Formula C22H14Cl2I2N2O2, molecular weight 663.1 g/mol. Its systematic (IUPAC) name is N-[5-chloro-4-[(4-chlorophenyl)-cyanomethyl]-2-methylphenyl]-2-hydroxy-3,5-diiodobenzamide. It is also known as 57808-65-8 (free acid) or KSC-18-157-1.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

As a reference sample of Closantel, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Closantel in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
