Uric acid is sparingly soluble in water, meaning it dissolves only to a limited extent. It has a melting point of 300-320 degrees Celsius and decomposes at higher temperatures. Chemically, uric acid is an organic compound belonging to the group of purine derivatives. Applicable Fields Medicine:...
A CAS number itself has no meaning. Its primary use is to avoid confusion between chemicals with similar names, or individual chemicals that may have multiple names. It is also used to identify the chemical when a generic or trade name is used. ...
