About Tamoxifen

Listed under CAS 10540-29-1, Tamoxifen is a high-purity reference standard of Tamoxifen available from Vaqora Chemicals. Its molecular formula is C26H29NO and its molecular weight is 371.5 g/mol. The IUPAC name is 2-[4-[(Z)-1,2-diphenylbut-1-enyl]phenoxy]-N,N-dimethylethanamine. It is also known as trans-Tamoxifen or Tamoxifene.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Under GHS it is labelled “Danger”, so handle it with suitable PPE and consult the SDS.

As a reference sample of Tamoxifen, 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.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
