Product Usage
Tetrabutylammonium iodide may be used as a mobile phase additive in ion-pair high-performance liquid chromatography (IP-HPLC) assay of 4-aminopyridine in serum. It may also be used as a mobile phase additive in the analysis of tetracycline by reversed-phase IPC. The addition of tetrabutylammonium iodide regulates the retention of tetracyclines.
Tetrabutylammonium iodide can be used:
As an additive in the synthesis of fused triazole derivatives using palladium catalyst.
To prepare allyl-PEG-allyl, which is a key intermediate polymer used to synthesize fluorinated amphiphilic copolymers.
As a catalyst used in the synthesis of ethers.
