About Cefradine delta-isomer
Cefradine delta-isomer is supplied as an analytical reference standard. It is registered under CAS number 150870-62-5.
The compound is characterised by its molecular formula C16H19N3O4S and a molecular weight of 349.40, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 349.1096 Da, a calculated LogP of 0.35, a topological polar surface area of 112.73 Ų. It presents 3 hydrogen-bond donors and 5 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: 2℃ ~ 8℃.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
