Synthetic Organic Chemistry
Spectrum Chemicals Australia
The science of synthetic organic chemistry has dramatically changed since urea became the first organic compound to be made from inorganic materials, in 1828. Literally thousands of useful organic compounds have been synthesized using a variety of novel reactions, catalysts, reagents, and synthetic techniques. These efforts continue with development of environmentally friendly organic synthetic techniques (i.e., green chemistry). In this section you will find lists reagents for various purposes including: polymer supported reagents and reagents for oxidation, reduction, condensation, protection, homogeneous metal complex catalysts and much more. contact us.
