Application: | Tetrazole solution is useful for DNA synthesis. It may be employed as a catalyst for the in situ synthesis of deoxyribonucleoside phosphoramidites. It may be used in the preparation of following anionic nucleotide-lipids: • thymidine 3′-(1,2-dilauroyl-sn-glycero-3-phosphate) , diC12-3′-dT • thymidine 3′-(1,2-dimyristoyl-sn-glycero-3-phosphate) diC14- 3′-dT • thymidine-3′-(1,2-dipalmitoyl-sn-glycero-3-phosphate) diC16- 3′-dT |
Caution: | Saturated solution at room temperature; storage below room temperature causes precipitation. |
General description: | The product is ~0.45M solution of tetrazole in acetonitrile. Tetrazole ring plays significant role in various synthetic and industrial processes. |
Other Notes: | Catalyst used in the phosphite triester method of oligonucleotide synthesis for the coupling of (dialkylamino)phosphines |
