Uses of Dimedone: Dimedone is a cyclic diketone used in organic chemistry to determine whether a compound contains an aldehyde group. And in general it can be used as catalysts in the formation of transition-metal complexes. Other uses include applications in colourimetry, crystallography, luminescence and spectrophotometric analysis. It can also be used for chemistry involving organic compounds of low electrical resistance. In addition, it is also used as reactant in many reactions, for instance, it can react with diacetoxy-phenyl-l3-iodane to obtain phenyldimedonyliodon at ambient temperature in ethanol for 30 min, yield is 82 %.

When you are using this chemical, please be cautious about it as the following: It is quite irritating to eyes, respiratory system and skin. When you are using this chemical, you should better wear suitable protective clothing and gloves to avoid contact with skin and eyes. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
