API Production from Development to Commercial Scale

API production requires more than reaction capacity. The production process must remain controllable as the molecule moves from laboratory development to larger-scale manufacturing.

Lianhe Aigen connects process development, scale-up and API manufacturing through an integrated production platform:

Process Development → Kilo-Scale Production → Pilot Production → GMP Manufacturing → Commercial API Production

Our Process Development team can support route and process development before the manufacturing stage, while the Production Technology Platform provides equipment and facilities for scale-up and production.

For projects requiring outsourced manufacturing execution, our Contract API Manufacturing service provides a separate pathway for technology transfer, process scale-up, GMP batch manufacturing, and clinical or commercial supply.

API Production Scale and Manufacturing Infrastructure

API manufacturing capacity must match the requirements of different development stages. Lianhe Aigen maintains production infrastructure covering laboratory, pilot, and commercial manufacturing.

Kilo-Level API Production Kilo-level laboratories provide a bridge between laboratory process development and larger-scale manufacturing. This stage can be used for process confirmation, material generation, and preparation for subsequent pilot or GMP production.

Pilot-Scale API Production Pilot plants allow process conditions, equipment configuration, and production procedures to be evaluated before commercial-scale manufacturing.

cGMP API Manufacturing cGMP multi-functional workshops support regulated API manufacturing and provide production infrastructure for pharmaceutical drug substances.

Commercial API Production Commercial manufacturing is supported by large-scale production equipment and multi-purpose production facilities designed for scalable API production.

Lianhe Aigen's production equipment includes 50 L to 20,000 L conventional reactors, with more than 1,000 sets, together with ultra-cryogenic reactors, high-temperature reactors, autoclaves, tubular/microchannel equipment, and high-vacuum distillation systems.

The platform supports reactions down to -100°C, high-temperature reactions up to 300°C, and hydrogenation at pressures up to 4 MPa.

For detailed GMP facility information, see API GMP Certified Factory.

Complex API and Specialized Chemistry

Complex API production often requires specialized reaction conditions, multiple synthesis steps, and dedicated process controls.

Complex multi-step synthesis
Hydrogenation and high-pressure reactions
Fluorination and nitration
Chiral synthesis
Enzymatic transformations
Cryogenic reactions
Flow and tubular/microchannel processing
High-temperature reactions
High-potency compound handling

The production platform is designed to accommodate different reaction conditions rather than relying on a single standard reactor configuration. This provides flexibility when a pharmaceutical synthesis route requires specialized temperature, pressure, or processing conditions.
