ChemSpider SyntheticPages (CSSP) is a free database of practical procedures for research workers in synthetic chemistry, written by chemists for chemists. The database is searchable by text terms or chemical structure. Chemists are encouraged to submit their own experimental information for inclusion in CSSP, and to comment on procedures submitted by others. ChemSpider SyntheticPages provides information that may not generally be found elsewhere, such as: frequently encountered problems, trouble-shooting tips,repeatability, and scalability.
