商品描述

Description

Glen Research H-Phosphonates are analyzed by HPLC and are synthesis-tested.H-Phosphonates are especially useful for the preparation of modified internucleotide linkages which are unattainable by phosphoramidite chemistry.The most popular application is the preparation of radiolabelled phosphorothioates, since the sulfurization reaction is carried out off the synthesizer.

Details

Usage

Coupling: H-Phosphonate Synthesis Protocol.|(The DBU is now being provided in place of the TEA salt for dC-H Phosphonate. This product shows better monomer stability and solubility.)
Deprotection: No changes needed from standard method recommended by synthesizer manufacturer.

Specifications
Diluent	Acetonitrile/Pyridine (1:1)
Storage	Refrigerated storage, maximum of 2-8°C, dry
Stability	~1week

Product FAQs

What are the concentrations of the solutions used on an ABI for H-phosphonate chemistry?
1. Adamantantanecarbonyl chloride - 2% w/v in 5%pyridine/acetonitrile.
2. Isopropyl phosphite - 1% in acetonitrile/pyridine (50:50)
3. Oxidation: Following synthesis
  1. React support with 4% Iodine in THF/Pyridine/Water ( 8:1:1) ~2mL for 4minutes
  2. Remove solution from support
  3. React support with mixture of 4% Iodine in THF/Pyridine/Water ( 8:1:1) (~1mL) and TEA/H2O/THF (8:1:1) (~1mL) for 3 minutes
  4. Flush column with acetonitrile and blow dry support
