# Small Molecule Chemicals: Synthesis and Applications
## Introduction to Small Molecule Chemicals
Small molecule chemicals are organic or inorganic compounds with low molecular weight, typically less than 900 daltons. These molecules play a crucial role in various industries, including pharmaceuticals, agriculture, and materials science. Their small size allows them to easily penetrate cell membranes, making them particularly valuable in drug development.
## Synthesis of Small Molecule Chemicals
The synthesis of small molecule chemicals involves several key methods:
### 1. Organic Synthesis
Traditional organic synthesis remains the backbone of small molecule production. This includes:
• Nucleophilic substitution reactions
• Electrophilic aromatic substitution
• Carbon-carbon bond forming reactions
### 2. Combinatorial Chemistry
This high-throughput approach enables the rapid synthesis of large libraries of compounds for screening purposes.
### 3. Biocatalysis
Enzyme-mediated synthesis offers environmentally friendly alternatives with high specificity.
