About Estradiol Benzoate

Vaqora Chemicals supplies Estradiol Benzoate, a high-purity reference standard of Estradiol benzoate registered under CAS number 50-50-0. Its molecular formula is C25H28O3 and its molecular weight is 376.5 g/mol. It is also known as Estradiol 3-benzoate or Oestradiol benzoate.

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 Estradiol benzoate, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Typical end-use sectors are 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.
