5-Chloro-1-[bis(dimethylamino)methylene]-1H-benzotriazolium 3-oxide hexafluorophosphate Chemical Properties,Usage,Production

Chemical Properties

White powder

Uses

Reagent for:
Synthesis of near-infrared pH activatable fluorescent probes
Synthesis of human β-amyloid by Fmoc chemistry
Stereoselective Horner-Wadsworth-Emmons olefination
Covalent ligation of fluorescent peptides to quantum dots
Alkylation of human telomere sequence

General Description

HCTU [1] is a novel aminium-based coupling reagent, analogous to HBTU, which in comparative studies was found to give superiort results to TBTU in the synthesis of difficult peptides [2], in hindered couplings [3], and cyclizations [4].

The product number for this product was previously 01-62-0038.
