About R-Cefadroxil Sulfoxide
R-Cefadroxil Sulfoxide is supplied as an analytical reference standard. It is registered under CAS number 182290-77-3.
The compound is characterised by its molecular formula C16H17N3O6S and a molecular weight of 379.39, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 379.0838 Da, a calculated LogP of -0.83, a topological polar surface area of 150.03 Ų. It presents 4 hydrogen-bond donors and 6 acceptors. The structure carries 4 defined stereocentres, which is relevant wherever a stereochemically defined standard is required. These values are commonly used to anticipate chromatographic retention and to plan ionisation conditions during method development.
Each pack ships with a certificate of analysis reporting purity of 95%+ together with the supporting analytical data — HNMR, MS and HPLC or GC traces — so the material can be released straight into your own QC workflow. Recommended storage: -20℃±5℃.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
