About Cefepime-d8 Sulfate

Cefepime-d8 Sulfate is a stable isotope labelled analogue related to Cefepime carrying the CAS registry number 131857-33-5. Formula C19H26N6O9S3, molecular weight 586.7 g/mol.

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. Handle it with standard laboratory precautions and appropriate personal protective equipment.

Its mass shift relative to the unlabelled analyte makes it a dependable internal standard for LC-MS/MS assays, improving accuracy in bioanalysis, therapeutic drug monitoring and method validation. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Cefepime-d8 Sulfate in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide. A Safety Data Sheet (SDS) and technical specifications are available on request.
