About Clindamycin Sulfoxide (S-Isomer)
Clindamycin Sulfoxide (S-Isomer) is supplied as an analytical reference standard. It is registered under CAS number 887607-49-0.
The compound is characterised by its molecular formula C18H33ClN2O6S and a molecular weight of 440.98, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 440.1748 Da, a calculated LogP of -0.59, a topological polar surface area of 119.33 Ų. It presents 4 hydrogen-bond donors and 7 acceptors. The structure carries 10 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.
