Reaction Monitoring

Process understanding and scale-up for pharma and biopharma

Overview

Rigorous process monitoring for pharma and biopharma applications

Reaction monitoring is critical for process understanding, optimization and scaling up, leading to cost savings, and ensuring the quality of the final product. It often provides important insights into the mechanism of chemical reactions, whether it is traditional chemistry, bioproduction or (bio)catalysis. Kinetic information can be extracted from the time course data and utilised to build kinetic models that will be used to predict conditions, enabling effective process optimisation as well as risk assessment and control.

A broad range of techniques can be used for process monitoring and perhaps in-situ vibrational spectroscopy is the most popular. A primary advantage of the use of FT-IR spectroscopy is that it can be readily employed at a variety of physical scales from small development reactors (<50 cm3 vessel volume) up to full scale manufacturing plants (>1000 L vessel volume). The fact that the measurement instrumentation can be configured to operate in situ whereby a measurement probe is inserted directly into the reaction vessel and connected to a spectrometer via a fibre optic cable means that little (or no) perturbation is caused to operation of the process. Additionally, the spectra are often rich in detail and can reveal high quality information about chemical composition and physical form.

However, it is rarely the case that data from FT-IR measurements would be employed in isolation. At the very least, companion data provided by techniques such as chromatographic assays, enthalpy measurements and structural elucidation studies will also be available from other activities carried out during synthetic route development and subsequent transfer.  Most of these techniques require a calibration step to normalize the output to give data on concentration versus time. NMR is able to play an important role in the calibration of other techniques as it provides an inherently quantitative signal response based on the number of nuclei, and it is also the primary structural elucidation tool for molecular characterization (including intermediates) ensuring that usually plays a strong role in the development of APIs.

Combination of FT-IR and NMR is a very powerful one, with the NMR also enhancing reaction understanding by gaining mechanistic insights. Online flow NMR mimics real reaction conditions, enabling time zero measurements and simultaneous acquisition with other spectroscopic. In combination with Mid-IR, it increases overall confidence when transferring process from the lab to the pilot or manufacturing plant. 

Process monitoring allows drug development teams to streamline workflows and reduce time taken to bring new small molecule and biologics drugs to market. 

Bruker has a wide portfolio of solutions and applications to monitor chemical and biological processes in order to increase the understanding of reaction mechanisms, the formation of radicals, the details of forced degradation, and the expression of cell metabolites.
