OrgSyn app brings all published procedures right to your fingertips. Search for full volume or single article or use full text search to find exactly what you are looking for. Share your findings with colleagues. Save hitlists and procedures to view them later, even offline. Since 1921, Organic Syntheses has provided the chemistry community with 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. Each procedure is written in considerably more detail as compared to typical experimental procedures in other journals, and each reaction with its characterization data has been repeated several times and carefully "checked" for reproducibility in the laboratory of a member of the Board of Editors. Organic Syntheses is published by Organic Syntheses, Inc., a non-profit corporation. Online Edition ISSN 2333-3553 Print Edition ISSN 0078-6209
