Chemistry: 2. Organic Chemistry

A database of 2483 organic compounds searchable by physical property. Each record contains molecular weight, density, index of refraction, boiling & melting points, and UV, IR, NMR, and Mass Spec peaks.

An integrated spectral database system for organic compounds, which includes 6 different types of spectra: mass spectrum, FT-Infrared, H-NMR, C-NMR, Raman, and ESR. Maintained by the National Institute of Advanced Industrial Science and Technology (AIST), Japan.

Since 1921, Organic Syntheses has provided the chemistry community with annual collections of detailed, reliable, and carefully checked procedures for the synthesis of organic compounds. Some procedures describe practical methods for the preparation of specific compounds of interest, while other procedures illustrate important synthetic methods with general utility.

Freely accessible database of organic chemicals with their synthesis references from major journals and a few basic physical properties.

Look up organic chemistry reactions by drawing a prototypical reactant and product.

Basic physical data (boiling point, density, aqueous solubility, relative polarity, etc.) on common organic solvents.

This site lists natural products with a heterocyclic ring system, collected from several dozen chemical journals from 1975-present, whose structure has been established. A companion site lists new syntheses as well.

Website has a helpful list of links, including organic data tables on a wide variety of topics.
