What is Custom Synthesis? Advantages, Challenges & Important factors

The article covers brief overview of what is custom synthesis, factors influencing custom synthesis, and advantages & challenges associated with it.

What is Custom Synthesis?

In the pharmaceutical business, which operates on a worldwide scale and is driven by innovation, custom synthesis is a crucial service that serves the company’s efforts in developing and expanding their product range. Custom chemical synthesis has deep roots in the process of drug discovery and development.

In custom synthesis, a corporation or customer requests that a molecule be produced specifically for them, at a certain scale, with the purity and using the specifications or processes specified by them.

Custom synthesis projects consisting of small-scale or low volume requirements which are generally for new molecules or molecules that are not commercially available are handled by organizations called CROs or Contract Research Organizations. For large-scale projects which include requirements of the chemical product in more than one ton quantity range, such projects should be handled by Contract Manufacturing Organizations or CMOs. Organizations that can handle all kinds of chemical research and manufacturing outsourcing requirements are a hybrid of CROs and CMOs, also known as CRAMs (Contract Research and Manufacturing).

Custom synthesis is one of the options open to drug developers in need of the active pharmaceutical ingredients (APIs) or other organic/inorganic chemicals to make their products effective if it is impossible or impractical for them to make these molecules and compounds in-house. It is a good idea to consider outsourcing the manufacturing of a product to professionals that specialize in the relevant sector.

It is a ritual in the industry that the contract is executed exclusively for the company giving out the contract and it is always done in accordance with confidentiality agreements. Custom synthesis can range in weight from a few milligrams to 10 kg or more.

Factors affecting Custom Synthesis

Before signing a contract for custom synthesis, there are a lot of crucial choices to make. A helpful framework for making decisions is to modify the “Four W’s”—Who, What, When, and Why—for obtaining information and solving problems.

Factors affecting Custom Synthesis

Who- The “Who” mostly relies on your unique requirements and volume, which might range from modest amounts of a reference standard to support a bioanalytical project to enormous amounts of API to support a clinical trial. For example – For large scale projects, you will want to consult with a large-scale Contract Manufacturing Organization (CMO). 

Your specific needs and scale can have a big impact on quality agreements, production systems, and contracting arrangements.

What- This includes a complete understanding of what kind of molecule you need. A complete research should be done in accordance with your material, regulatory and facilitatory requirements which will help you in selecting the correct organization.

When- At what point of your development process, you feel the need for customized synthesis of any molecule, also plays an important role. You may require procuring milligram to multi-gram amounts of reference standards, internal standards, impurities, or radiolabeled materials produced by custom synthesis.

It is essential to provide adequate lead time for the acquisition of starting material, the actual synthesis, and any other deliverables (such as a Certificate of Analysis). As the chemical or procedural complexity of a synthetic scheme rises, so does the necessary time. Timing will also rely on the regulatory method; cGMP synthesis, for example, will take substantially longer than a non-regulatory project.

Why- Even though it comes at the end of the list of the four W’s, this is the very first question that you need to ask before moving forward with a custom synthesis. A well-designed study should always come first in order to prevent difficulties in subsequent stages.

Other factors affecting Custom Synthesis-

It can be difficult to choose an outsourcing partner that is compatible with your company’s guiding principles and that also enhances your core competencies as a business. Some of the conditions that may affect your choice of Contract research organization (CRO) are as follows :-

  • The primary domain of expertise held by the CRO.
  • The size of the CRO.
  • The performance history of the CRO.
  • The financial stability of the CRO.
  • The certificates held by the CRO (ISO 9001, cGMP).
  • Other soft factors relating to CRO like location, communication (language), partnership, ownership, trust (confidentiality and IP protection).

The end goal of custom synthesis is to make the process safe, sound, and replicable in order to achieve the highest level of production efficiency as is humanly achievable.

Advantages of Custom Synthesis

  • Extra external scientific and technological input.
  • Time saving.
  • Resources and cost optimization.
  • Choice of an “extended workbench” without the requirement to make significant investments in one’s own employees or workplace.
  • Accessibility to complex target structures and materials

Challenges in Custom Synthesis

Custom synthesis proves to be a complex process for difficult projects, but many companies are traditionally on tight timelines. There is always a risk associated with the completion of the project within the deadline.

Also, trusting an organization with all your sensitive and confidential information also possess great risk. You need to hire a reputed legal consultant who can draft a stringent confidentiality agreement for you to avoid breach of confidentiality.

FAQs

Q. What are the types of Chemical Synthesis ?

One of the most important categories of chemical reactions is called the synthesis reaction, including reactions such as halogenation reactions, condensation reactions, oxidation reactions, coupling reactions, cyclisation reactions etc.

Q. Is contract research and custom synthesis a service that can only be provided to large pharmaceutical companies?

Absolutely not. This service does not focus on a specific demographic of clients and is not dependent on any one particular business.
