Read and save structures in various chemistry file formats. Determine if one structure is a substructure of another (substructure matching). Determine if two structures are equal (exact matching). Identification of substructures common to structures in a set (maximal common substructure, MCS). Disassemble molecules, splitting into fragments.
Computer-assisted organic synthesis software is a type of application software used in organic chemistry in tandem with computational chemistry to help facilitate the tasks of designing, predicting, and producing chemical reactions. CAOS aims to identify a series of chemical reactions which, from a starting compound, can produce a desired molecule.
A chemical graph generator is a software package to generate computer representations of chemical structures adhering to certain boundary conditions. The development of such software packages is a research topic of cheminformatics .

Reference Organizer presents all references in graphical user interface, where you can choose whether the references should be defined in the body of article or in the reference list template(s) (list-defined format). You can also sort the references in various ways (and optionally keep the sort order), and rename the references.
Protactinium-231 is the longest-lived isotope of protactinium, with a half-life of 32,760 years. In nature, it is found in trace amounts as part of the actinium series , which starts with the primordial isotope uranium-235 ; the equilibrium concentration in uranium ore is 46.55 231 Pa per million 235 U.
Citation templates have been created for a number of commonly used textbooks: some examples are given below, and the complete list can be found at Category:Chemistry citation templates. Please include page numbers or page ranges ( page = or pages = parameters respectively) when using these templates.
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
