Understanding API Intermediates

Active Pharmaceutical Ingredients (APIs) are the key substances in finished pharmaceutical products. APIs give medications their identity and pharmacological activity for disease diagnosis, treatment or prevention. These are chemical compounds produced during the multi-step synthesis of an active pharmaceutical ingredient (API). APIs are the biologically active components of drugs, and their production is a complex process involving numerous chemical reactions and purification steps. Each step generates an intermediate compound that is subsequently used to chemically transform into the next intermediate. These intermediates build toward the final API molecule. API intermediates allow for the step-wise assembly of complex drug molecules and are often purified and isolated for use in further reaction stages. They are crucial to efficiently manufacturing APIs at commercial scales.

At Aquigen, we focus on developing specialized intermediates through precision chemical synthesis. A wide variety of drug molecules rely on our intermediates for both large-scale production and early R&D activities. As a trusted Contract Development and Manufacturing Organization, we produce intermediates and APIs adhering to the highest quality and compliance standards. Our goal is to support pharmaceutical partners from lab to commercialization through efficient, cGMP-compliant manufacturing processes. In addition to API/intermediate synthesis, we offer analytical testing services and process impurity isolation to help expedite client development timelines. All of our products and services are designed strictly for research purposes. Aquigen is committed to streamlining the drug development process from concept to market!

Sources of Impurities in Drug Substances

Organic Impurities

Organic impurities in active pharmaceutical ingredients can be either drug-related or process-related. They include identified specified impurities, unidentified specified impurities, and total unknown impurities.

Process-related impurities arise during chemical synthesis and manufacturing as residual unreacted materials or side reactions. Degradation-related impurities are generated when the active ingredient breaks down under certain storage conditions, such as oxidation or dehydration.

The active ingredient’s interaction with excipients, containers or residual impurities in solvents and reagents can also lead to degradation-related impurities. Even with washing and purification steps, residual unreacted materials from the synthesis process may remain as potential process-related impurities unless manufacturing is carefully controlled.

What are the different sources of Impurities in Drug Products?

Impurities in pharmaceutical drug products can come from the drug substance’s degradation or may be formed during various stages such as processing, formulation, and storage, involving factors like excipients used and processing-related degradation, etc.

Importance of Testing Impurities

The presence of impurities beyond acceptable criteria could impact the identity, quality, safety and efficacy of active pharmaceutical ingredients and drug products. Impurities may also accelerate active ingredient degradation and negatively impact stability posing serious concerns. Therefore, thorough qualitative and quantitative impurity analysis is essential. Identifying and measuring impurity levels (Impurity Profiling) represent critical quality attributes carefully reviewed by regulators. Pharmacopeias and ICH provide specified impurity limits and thresholds that products must meet prior to human use. Adherence to these impurity specification guidelines through analytical testing is mandatory to ensure appropriate product release for consumption.
