What are functions of pharmaceutical intermediate

Pharmaceutical intermediates are chemical compounds that serve as precursors or building blocks in the production of active pharmaceutical ingredients (APIs). They are not the final drug but are used in the synthesis process to ultimately create it.

Functions of Pharmaceutical Intermediates

Stepwise Synthesis

Intermediates enable the step-by-step construction of complex molecules by reacting in a specific sequence to eventually produce the desired API.

Process Optimization

They allow better control over reaction conditions, purification steps, and yields. This improves efficiency, scalability, and cost-effectiveness of drug manufacturing.

Quality Control & Consistency

Using defined intermediates helps ensure consistent quality of the final API by reducing variability in synthesis.

Customization & Flexibility

Different intermediates can be used to produce analogues or derivatives of drugs, enabling the creation of new formulations or modified-release products.

Regulatory Compliance

Documenting the use of intermediates in a validated synthesis pathway is essential for regulatory approval from authorities like the FDA or EMA.

IP and R&D Advantage

In research and development, intermediates can be used to test various synthetic routes or optimize yields before finalizing a production process.

Example

To produce the API paracetamol (acetaminophen), a common intermediate is p-aminophenol. It reacts with acetic anhydride to form the final API.
