Organic semiconductors are an important class of functional materials. Numerous molecular and polymeric organic semiconductors have been developed for their great potentials in next generation flexible and printed electronics. The Heterocyclic Building Blocks are organized based on the heteroatom(s) that are present in their structures, including sulfur-, nitrogen-, silicon-, phosphorus-, and boron-containing heterocycles.

Unsaturated heterocycles are popular in bioactive compounds and drugs. Herein, Aladdin offer a library of heterocycles with two halogen atoms bearing different activity. They can be used for the stepwise nucleophilic substitution followed by a metal-mediated cross-coupling to produce the functionalized products.

Heterocyclic Building Blocks? are probably the largest and most varied family of molecular fragments used by chemists for organic synthesis. Many of the heterocyclic scaffolds have been identified as a privileged structure in medicinal chemistry and are prevalent in a variety of pharmacologically active synthetic and natural compounds. Most chemical reaction design planning starts from these commercially available building blocks. By combining our core offering with a diverse suite of partners’ compounds, Aladdin have the industry’s most comprehensive selection of heterocyclic building blocks. Providing your chemical synthesis with our one-stop source of chemical reagents.
