Raw Material Selection

API production begins with careful raw material selection. Suppliers must meet GMP standards and provide full traceability documentation. In addition, incoming materials undergo identity testing, purity verification, and risk assessment to ensure consistent quality.

According to ICH Q7 guidelines, proper raw material control is essential for API quality assurance.

Process Development

Once raw materials are approved, process development defines the synthetic route, reaction conditions, and purification strategy. Moreover, this stage optimizes lab-scale procedures to ensure commercial-scale reproducibility, safety, and efficiency.

Chemical Synthesis

Chemical synthesis is the core of API production. Reaction parameters such as temperature, pressure, pH, and time are tightly controlled to maximize yield and minimize impurities. In addition, real-time monitoring ensures consistent batch performance and regulatory compliance.

Purification

After synthesis, APIs undergo purification via crystallization, filtration, extraction, or chromatography. Furthermore, these processes remove impurities and isolate the desired compound at the required purity level. As a result, the final product maintains stability and quality.

Drying

Purified APIs are dried to remove residual solvents and moisture. In addition, drying ensures that the material reaches the correct physical properties for downstream processing. Proper drying is essential for stability, handling, and storage.

Particle Size Control

After drying, APIs are milled to achieve specific particle size distributions. Moreover, particle size affects solubility, bioavailability, and downstream formulation performance. Therefore, controlled milling is critical to meet formulation requirements.

Quality Control and Testing

Throughout API production, quality control verifies identity, potency, purity, and safety. Techniques such as HPLC, GC, IR, and mass spectrometry ensure compliance with pharmacopeial standards. In addition, consistent analytical testing supports reliable production and regulatory filings.

Refer to USP analytical testing standards for API quality control.

Regulatory Compliance

Regulatory compliance is integrated into every stage of production. Moreover, comprehensive documentation, batch records, validation reports, and stability studies support regulatory filings and inspections. Adherence to global standards ensures APIs meet international market requirements.

Packaging and Storage

Finished APIs are packaged in validated containers that protect against moisture, light, and contamination. In addition, proper storage conditions and controlled logistics maintain product integrity. As a result, APIs arrive safely at formulation facilities worldwide.
