About Sildenafil Citrate

Sildenafil Citrate (CAS 171599-83-0) is a high-purity reference standard of Sildenafil offered by Vaqora Chemicals. With the molecular formula C28H38N6O11S, it has a molar mass of 666.7 g/mol. It is also known as Actra-Rx or Alisiga.

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. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

As a reference sample of Sildenafil, 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. This item is currently in stock for prompt dispatch.
