Chemistry and Chemical Engineering
This database allows users to search the NLM ChemIDplus database of over 370,000 chemicals. A user may enter compound identifiers such as Chemical Name, CAS Registry Number, Molecular Formula, Classification Code, Locator Code, and Structure or Substructure. New searchable features include search and display by Toxicity indicators such as Median Lethal Dose (LD50), by Physical/Chemical Properties such as LogP, and by Molecular Weight.
The Beilstein Handbook of Organic Chemistry is one of the most comprehensive collections of data on the properties, preparation, and reactions of carbon compounds. It is organized by structure (acyclic, isocyclic, and heterocyclic compounds). Unlike Chemical Abstracts which tries to publish everything in chemistry, Beilstein is selective. The editors have published only critically reviewed data.The Beilstein Handbook of Organic Chemistry covers the literature from 1779 through 1979.
