설명
Acetone-1,3-dicarboxylic acid is used as a building block in organic chemistry. It is also used in the synthesis of hetrocyclic rings and in the Weiss-Cook reaction, which involves the preparation of cis-bicyclo[3.3.0]octane-3,7-dione by reacting with diacyl (1,2 ketone). Its presence in human urine is used as a diagnostic test for the overgrowth of harmful gut flora such as Candida albicans.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand.
