1. What is the structural analysis of organic molecules?
I will clearly explain the features of NMR, MS, and single crystal X-ray structure analysis, as well as the challenges of structural analysis.
In research and development of organic compounds, quality assurance, and intellectual property strategy, accurately understanding the structure of compounds is important. However, in practice, there are many challenges such as insufficient sample amounts, difficulties in crystallization, and determining absolute configuration. This document provides a clear explanation of the characteristics and roles of NMR, MS, IR, and single-crystal X-ray structure analysis as the foundation for structural analysis of organic molecules. It also introduces the challenges faced in the structural analysis of organic molecules and one of the solutions, the "crystal sponge method." ▼ Recommended for ▼ - Those who want to know the differences in structural analysis methods - Those considering the structural determination of unknown components or impurities - Those facing challenges in determining absolute configuration - Researchers and developers in the fields of pharmaceuticals, chemicals, fragrances, and natural products - Those who want to know the latest trends in structural analysis technology *For more details, please download the PDF or feel free to contact us.

Daicel utilizes structural analysis techniques, including the crystal sponge method, to provide new options for absolute configuration determination and structural determination. In general manufacturing and research and development settings, there are numerous challenges such as: - "The structure is too complex, and I am unsure if the estimated structure is correct using GC-MS or NMR." - "I cannot even estimate the structure because I can hardly obtain any quantity." - "I cannot perform single crystal X-ray structural analysis because I cannot crystallize it." At our center, by combining the crystal sponge method, single crystal X-ray structural analysis, and our unique structural analysis techniques, we offer optimal analytical approaches to structural determination challenges that are difficult with existing methods. Additionally, we possess dozens of unique crystal sponges and are working on applications to a wide range of compounds. We can also collaborate with column separation and purification services as needed, providing solutions that encompass everything from separation to structural determination.
