About Zeranol

Zeranol (CAS 26538-44-3) is a high-purity reference standard of Zeranol offered by Vaqora Chemicals. With the molecular formula C18H26O5, it has a molar mass of 322.4 g/mol. Systematically, it is named (4S,8R)-8,16,18-trihydroxy-4-methyl-3-oxabicyclo[12.4.0]octadeca-1(14),15,17-trien-2-one. Alternative names: Zearalanol and alpha-Zearalanol.

The product is provided as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

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

We offer Zeranol in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
