API Characterization

Serán’s pre-formulation assessment begins with an in-depth understanding of our client's API and project goals and timelines, right from the start. We use a science-first approach to conduct detailed research into your molecule and state-of-the-art technologies enable us to develop optimized formulations, processes, and analytical methods for your project. We leverage a full suite of analytical capabilities and modeling tools to assess your API with a drug product mindset.

Early-Phase Formulation Optimization Accelerates and De-Risks Development Right from the Start

We first characterize the API’s physical characteristics and solution behavior, allowing us to rationally select optimal approaches and customize development plans to holistically evaluate formulations and select leads that balance performance, processability, and stability.

Serán’s team of chemists and engineers characterizes API solid-state properties and solubilities in work plans customized to meet each program's unique needs. Our Analytical team collects data that can be leveraged with our bio-performance model to identify opportunities and risks for drug product development using only milligram quantities of API.
