Derivatization is the process by which a compound is chemically changed, producing a new compound that has properties more amenable to a particular analytic technique. As a key separation method, derivatization provides:

• Increased volatility, thermal stability, and peak shape • Improved selectivity and chromatographic effciency • Strengthened detectability

J&K provides an extensive selection of derivatization reagents, including those used for GC and HPLC analysis, chiral separations and TLC applications. By choosing the right derivatization reagent and procedure you can increase resolution and analytic response, signifcantly improving your separations.

Scientifc ey lement or our Success Natural Products

Organic chemists and medicinal chemists have been interested in natural products for a long time. Natural products are the inspiration for about one half of the drugs approved by the U.S. Food and Drug Administration. Only about 5-15% of the approximately 250,000 species of higher plants and less than 1% of the microbial world (including marine organisms) have been systematically investigated chemically so far - this leaves vast untapped resources and illustrates the tremendous potential for development in the area of natural medicine.

J&K provides a variety of natural products which are sourced from plants, animals and microorganisms.
