Summer Intern, Organic Synthesis
Hercules Incorporated, a world leader in water-soluble polymers, paper
chemicals, water treatment, resins, food gums, and non-woven fibers,
is seeking a summer intern to carry out synthesis, purification and
characterization of fluorophore-labelled oligo- and polysaccharides
following published protocols. Candidate reactions include:
* Derivatization of the reducing end by Schiff base formation
with amines.
* Activation of the carboxylic groups in acidic saccharides
with a carbodiimide followed by coupling to an amine.
* Preparation of functionalized spironaphthoxazines by condensing
Fischer's base with a selected naphthol. The functionalized
molecule will be covalently linked to the polysaccharide.
Qualifications: Must be at least a junior in college, have organic
synthetic skills, and be able to work quasi-independently. A basic
knowledge of fluorescence spectroscopy will be helpful but is not
essential.
