General description

1-(p-Toluenesulfonyl)imidazole converts alcohols to azides in one step.

Application

1-(p-Toluenesulfonyl)imidazole was used in the synthesis of cationic water soluble cyclodextrin, mono-6A-(1-butyl-3-imidazolium)-6A-deoxy-β-cyclodextrin chloride (BIMCD), useful in chiral separation of amino acids and anionic pharmaceuticals by capillary electrophoresis.

Ciprofloxacin is a broad-spectrum fluoroquinolone antibiotic used to treat bacterial infections; however, its limited aqueous solubility inhibits its broader clinical uses. This study investigated the complexation effect of mono-6-deoxy-6-aminoethylamino-β-cyclodextrin on the aqueous solubility and bioavailability of ciprofloxacin. During complexation, the

We describe a protocol for the synthesis of mono-6(A)-(1-butyl-3-imidazolium)-6(A)-deoxy-beta-cyclodextrin chloride (BIMCD), a cationic, water-soluble cyclodextrin used in the chiral separation of amino acids and anionic pharmaceuticals by capillary electrophoresis. Starting from commercially available chemicals, BIMCD is synthesized in five steps.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
