Tocopherol Phosphoramidites

Vitamin E is both lipophilic and non-toxic even at high doses so would be an excellent candidate as a lipophilic carrier for oligonucleotides. Therefore, as an addition to our cholesteryl product line, we offer simple α-tocopheryl (vitamin E) labelling. Totally synthetic α-tocopherol is racemic at its three chiral centers and is used to prepare this product.
