Ammonia or azane is a compound of nitrogen and hydrogen with the formula NH3. It is a colourless gas with a characteristic pungent smell. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia either directly or indirectly is also a building-block for the synthesis of many pharmaceuticals and is used in many commercial cleaning products. Although in wide use ammonia is both caustic and hazardous.
