About Methyl Levocamphorsulfonate
Methyl Levocamphorsulfonate is supplied as an analytical reference standard. It is registered under CAS number 83603-04-7.
The compound is characterised by its molecular formula C11H18O4S and a molecular weight of 246.32, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 246.0926 Da, a calculated LogP of 1.36, a topological polar surface area of 60.44 Ų. It presents 0 hydrogen-bond donors and 4 acceptors. The structure carries 2 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.
