In the last decade, high-resolution mass spectrometry (HRMS) has emerged as a powerful technique in many fields of biological studies, pharmaceutical and nutraceutical research and environmental analysis. The result is a route scouting service that is already helping to mitigate API complexity and accelerate small molecule drugs’ route to market.

It combines Elsevier’s Reaxys technology with Lonza’s real-world experience and supply chain insights. In this white paper, we look at how our two companies have worked together to develop a retrosynthesis process that meets the needs of process chemists in Lonza’s Preclinical Route Design group. Taken together, these issues mean there is a significant risk that development timelines may not be met.Īs a result, computer-aided synthesis design technologies (CDSTs) have been developed to assist in finding the most effective synthetic route for a given molecule. Supply chain complexity is a knock-on concern that can also add to costs. This adds to the issues facing process chemists as they look for a cost-effective and high-yielding synthesis for scale-up and commercialisation. The increasing complexity of small molecules entering the drug development pipeline is a real challenge, not least because the synthetic routes to make them are often long. In addition, predictive technology provides us with a wide range of information with limited experimental data and resources. Predicting the solubility in various binary solvent systems makes it easier to select the most appropriate solvent system to optimize the crystallization process. In this app note, we exemplify how measured solubility data in various water-alcohol binary solvent systems and the Jouyban–Acree model can be used to predict solubility as a function of temperature and solvent composition. Alcohols for example, are often used as co-solvents in aqueous solutions altering the solubility and other crystal attributes. Knowing the solubility will allow you to select suitable solvents for the different crystallization methods. The solubility of your compound in organic solvents or water plays an important role when designing or optimizing your crystallization process. 70% of all solid materials produced in chemical industry are obtained by crystallization or precipitation from solution.
