94-20-2 Usage

Purification Methods

Crystallise the urea from aqueous EtOH. [Beilstein 11 IV 119.]


For treatment of NIDDM in conjunction with diet and exercise.

Fire Hazard

Flash point data for CHLORPROPAMIDE are not available; however, CHLORPROPAMIDE is probably combustible.

Reactivity Profile

A halogenated amide. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).


Chlorpropamide is a sulfonylurea derivative. Chlorpropamide is a long acting hyopglycemic agent. Chlorpropamide is used in the treatment of diabetes metilus type 2. Chlorpropamide acts to increase the secretion of insulin and is not effective in patients who do not have pancreatic beta cell function.
