Descripción

General description

The product is ~0.45M solution of tetrazole in acetonitrile. Tetrazole ring plays significant role in various synthetic and industrial processes.

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.

Other Notes

Catalyst used in the phosphite triester method of oligonucleotide synthesis for the coupling of (dialkylamino)phosphines
