Chemistry resources is a collection of links and references that are useful for chemistry-related work. This includes free online chemical databases , publications, patents , computer programs , and various tools.
PubChem is a database of chemical molecules and their activities against biological assays.The system is maintained by the National Center for Biotechnology Information (NCBI), a component of the National Library of Medicine, which is part of the United States National Institutes of Health (NIH).
Mellitic acid, which contains no C-H bonds, is considered a possible organic compound in Martian soil. [15] Terrestrially, it, and its anhydride, mellitic anhydride, are associated with the mineral mellite (Al 2 C 6 (COO) 6 ·16H 2 O). A slightly broader definition of the organic compound includes all compounds bearing C-H or C-C bonds.
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1]
A chemical database is a database specifically designed to store chemical information. This information is about chemical and crystal structures , spectra, reactions and syntheses, and thermophysical data.
If a spectrum of an unknown chemical compound is available, a reverse search can be carried out by entering the values of the chemical shift, frequency or mass of the peaks in the NMR, FT-IR or EI-MS spectrum respectively. This type of search affords all the chemical compounds in the database that have the entered spectral characteristics. [6]
Chemical libraries are usually designed by chemists and chemoinformatics scientists and synthesized by organic chemistry and medicinal chemistry. The method of chemical library generation usually depends on the project and there are many factors to consider when using rational methods to select screening compounds. [2]
