About Erythromycin Ethylsuccinate-13C-d3
Erythromycin Ethylsuccinate-13C-d3 is supplied as an analytical reference standard. It is registered under CAS number 1264-62-6.
The compound is characterised by its molecular formula C42[13C]H72D3NO16 and a molecular weight of 866.06, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 865.5308 Da, a calculated LogP of 2.68, a topological polar surface area of 226.28 Ų. It presents 4 hydrogen-bond donors and 17 acceptors. The structure carries 18 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.
