High-quality intermediates lay the foundation for successful API development and commercial manufacturing. Poor impurity profiles, inconsistent critical quality attributes, or insufficient batch-to-batch consistency often lead to failed downstream reactions, low purification yields, and compromised quality of the final API and drug product.

AkTilin™ is AKTINPHARM^®’s dedicated intermediate product line developed for pharmaceutical enterprises, biotechnology companies, and Marketing Authorization Holders (MAHs). Rather than merely delivering pharmaceutical intermediates that meet the required quality specifications, we dive deep into synthetic-route chemistry, process control, impurity profiles, and quality research to deliver intermediates with well-defined impurity profiles, fully characterized structures, stable physical properties, and excellent batch-to-batch reproducibility tailored for subsequent API workflows.

Supported by three proprietary platforms — Phytopower^® Development Platform of Bioactive Molecules & Ingredients from Global Medicinal Plants, Aktinsyn^® Technology Platform of Synthetic Chemistry, and Aktinbio^® Development Platform of Biotechnology—and integrated with our R&D and manufacturing infrastructure and CRDMO capabilities, AkTilin ™ covers the full project lifecycle from early development through to commercialization. 

Why Work with AkTilin™ ？

Process Understanding: Robust, scalable synthetic routes established through process research and route evaluation, optimized for safety, quality, and manufacturing efficiency.
Consistent Quality: Management of critical quality attributes via analytical control systems and systematic impurity profiling to ensure batch-to-batch consistency.
Scalable Supply: Transition from laboratory development, process optimization, and pilot scale-up to commercial-scale manufacturing supported by our technical infrastructure, maintaining quality consistency across various production scales to meet material requirements at different project phases.
Technical Partnership: Access to process R&D, analytical, and manufacturing teams to provide technical support throughout the duration of API development projects.

Connected Development Support: From Intermediate to API

AkTilin ™ intermediates are integrated with the broader AKTINPHARM® pharmaceutical development and manufacturing platform to support process transitions from intermediate scale-up through to commercial API production:
Route Screening: Identification and evaluation of practical synthetic pathways with consideration of quality, cost, safety, environmental impact, and scale-up potential to establish chemical routes suitable for R&D and commercial manufacturing.
Process Development: Optimization of reaction conditions, raw materials, process parameters, work-up, and purification protocols to establish reproducible manufacturing processes with scale-up potential.
Impurity Understanding: Characterization, isolation, and control of process-related impurities to ensure intermediate quality satisfies downstream API development and quality control requirements.
Scale-Up & Technical Transfer: Stepwise translation of chemical processes from laboratory development to pilot and commercial-scale manufacturing through technical transfer protocols and parameter optimization.
Analytical Support: Development of analytical methods, testing validation, and quality research supporting both intermediates and APIs.
Commercial Manufacturing: Flexible manufacturing capacity designed to support customer project milestones as pipelines progress from development to commercial volume requirements.
