About Cefadroxil Ethyl Homolog
Cefadroxil Ethyl Homolog is supplied as an analytical reference standard. It is registered under CAS number 2243976-70-5.
The compound is characterised by its molecular formula C17H19N3O5S and a molecular weight of 377.41, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 377.1045 Da, a calculated LogP of 0.54, a topological polar surface area of 132.96 Ų. It presents 4 hydrogen-bond donors and 6 acceptors. The structure carries 3 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.
