Understanding 4-Nitrophthalimide

The chemical industry has become an integral part of the economy. The industry has a wide spectrum of category which includes both forms of chemical compounds that includes organic and inorganic chemicals which are used in a variety of applications. The production of chemical compounds or substances goes hand in hand with the storage as both the task is very tedious, which needs special attention. The product 4-Nitrophthalimide is a pale yellow colored powdered substance which is being used in pharmaceutical and dyestuff industries. The product has been accepted globally and further research and developments is about to make the product more usable to meet the customer demands.

There are other synonyms which are associated with these derivatives and are known as:
  • 4-Nitro-1
  • Imide 5-Nitrophthalimide
  • 2-Benzene Dicarboxylic acid
  • 3 (2H) -DIONE 5-NITRO-1
  • 3-Dione, 5-Nitroisoindole, 5- Nitroisoindoline
The powdered substances are sparingly soluble in water, alkali and acetone. Hydrolysis is a possibility. This belongs to the reactive group of amines, pyridines, phosphines, Nitro, nitrate and nitrate compounds, nitroso and organics.

Chemical properties of 4-Nitrophthalimide:
  • Empirical formula: C8H4N2O4
  • Molecular weight:  192.13
  • Purity                 :   99% min
  • Melting point:         201 to 202 degree Celsius
  • Water solubility  :   Less than 0.01 g/100 ml at 18 degree Celsius
  • Density               :  1.609g/cubic cm
This chemical compound is a nitrate amine and the amines are generally combustible. The amines are chemical bases to neutralize the 5-Nitro salicylic acid which help in the formation of salt water. This formation of acid base is exothermic. This chemical is stable, combustible and incompatible with water, moisture, strong bases and strong oxidizing agents. The storage requires to be maintained in a tight and closed container. The room should be cool, dried, well ventilated and should be kept away from substances which are incompatible. The incompatible absorbents are:
  • Mineral based and clay based absorbents
  • Cellulose based absorbents
  • Expanded polymeric absorbents

4-Nitrophthalimide is used in pharmaceutical industries and features in a basic Intermediate of Cetalopam Drug and is utilized in the making of anti depression drugs. The powdered substances and intermediates are being checked under properly defined parameters which ensure flawless range to the customers.
