Analytical Chemistry

Analytical Testing

Analytical testing is a fundamental component to the analytical chemistry group at Nalas.  We have a wide range of techniques available include but are not limited to general titrations, density measurements, refractive index, residual water content, residual solvent content, DSC and TGA, Raman, FTIR, UV-Vis, LC, SFC/MS, LC/MS (including UPLC), GC/FID/MS, ion chromatography, GPC, accurate mass measurement, and NMR spectroscopy. These technologies and the requisite techniques are the cornerstone to our analytical capabilities here at Nalas Engineering. 

Structural Elucidation

Structure elucidation is critical to any chemistry-related project. The appropriate identification and characterization of synthetic materials, impurities, metabolites, etc. provides insight into many aspects of chemical processes, whether medicinal chemistry, process chemistry or metabolism.  We have state-of-the-art capabilities and the knowledge to solve a vast array of structure elucidation problems. Our capabilities allow us to elucidate chemical structures via modern analytical methodologies allowing for complete assignment for all reporting needs, whether in the scientific literature or a regulatory filing. Our team of scientists have the knowledge and capabilities to provide solutions to your structure elucidation needs. 

Method Development 

Chromatographic method development is a critical skill set in any analytical group performing work on small molecules. Nalas has a great deal of expertise in method development ranging from purity determining methods to methods designed for component isolation.  We have a diverse array of chromatographic techniques at our disposal. These include HPLC/UPLC, SFC, GPC, IC, with a wide array of detection methods to aid in the development of the needed separation.

Flow NMR

Reaction monitoring via NMR spectroscopy provides significant insights into reaction kinetics, impurity profiles and mass balance across all NMR observable species being studied. The data is inherently quantitative during the course of the reaction. Therefore, one can collect quantitative data of all starting materials, intermediates, impurities and products over the entire course of the reaction. Here is an example of this application for the hydrolysis of acetic anhydride.

At Nalas, we provide high resolution (400 MHz) for reaction monitoring via NMR spectroscopy.  Our Bruker NEO 400 MHz spectrometer is equipped with an InsightMR™ accessory for collection of real time NMR data.  InsightMR™ by Bruker is a FlowNMR technology that combines hardware and software into one solution for online monitoring of chemical processes for real-time understanding and optimization.

Impurity Profiling

Impurity profiling goes hand in hand with method development and structure characterization. Being able to adequately develop a method to observe the impurities in a particular chemical transformation is an important step in understanding material balance, fate and purge and degradation. Having the ability to not only observe but to characterize the impurities via MS or potentially NMR has tremendous impact in process understanding.

Solid-State Chemistry

As experts in solid-state chemistry, Nalas offers salt, cocrystal and polymorph screening to encompass the full solid-state landscape that one may encounter in preparation for full-scale production and preparation of patent estates. Full analytical characterization of new and known solid-state forms is available to meet short development timelines and emergency in-the-tank trouble shooting. To assess the physical properties of crystalline material, advanced techniques in solid-state characterization are employed, which include Single Crystal X-Ray Diffraction (SC-XRD), Powder X-ray Diffraction (P-XRD), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Optical Microscopy, and High Performance Liquid Chromatography (HPLC) for solubility determinations.

The study of crystallization bridges the disciplines of chemistry, materials science, and engineering.  Through crystallization a collection of randomly orientated molecules in solution (or from a disordered semisolid) are assembled into a highly ordered solid-state through pair-wise molecular and atomic interactions. Characterizing the solid-state of new molecules or molecular complexes drives the fundamental understanding of their physicochemical properties and thus facilitates efficient development for bulk chemical production, fine chemical research, pharmaceutical development, and highly energetic materials development. The Nalas team will construct a crystallization process map to navigate the solid form landscape of polymorphs and solvates to isolate finished goods in high yield and purity.

 

Isolation by precipitation or crystallization requires fundamental knowledge of a systems kinetic and thermodynamic properties such as solubility, supersaturation, desaturation rate,
dissociation constant (pKa), and Vapor Liquid Equilibria (VLE) in order to map the solid form
landscape.
