Ammonium Hydroxide

High Purity, Customisable Concentration

Ammonium Hydroxide


Ammonium hydroxide is a compound which is formed by the reaction between ammonia and water molecule. Ammonium hydroxide is also commonly known as aqueous ammonia, aqua ammonia, ammoniacal liquor, ammonia liquor or ammonia water.



Ammonium hydroxide has a pungent and characteristic odour of drying urine and is a colourless solution in its pure form. Being alkaline in nature it is commonly use as acid neutraliser.



It is a building-block for the synthesis of many pharmaceuticals and is used in many commercial cleaning products. It is also commonly used in resins, agriculture, water treatments, electronics and agent in food processing.

Ammonium hydroxide is also widely used for the sanitation purpose as it is effective in masking microbial agents.

Other information


Ammonium hydroxide is corrosive to copper, copper alloys, aluminum alloys and galvanized surfaces. It is an excellent acid neutralizer. Its pH varies with concentration.

Regulatory Classification

Due to ammonium hydroxide’s toxic properties, its use is usually regulated and monitored worldwide. It is a hazardous substance and is classified as under UN Hazard Class 8 with UN Pack Group III.


Ammonium hydroxide solution exerts vapor pressure which varies with temperatures. It should be stored in a closed container and kept cool at all times. Otherwise, the ammonia gas will escape out of solution and the material concentration will be reduced over time. In addition, do not completely filled closed containers to avoid overpressurisation due to unexpected increment of temperature .


Precautions must be taken when handling ammonium hydroxide. As it has high pH level, direct contact may cause severe skin, eye and respiratory tract irritation and may lead to tissue burns. Inhalation of ammonium hydroxide mists may cause burning sensation in nose and may lead to pulmonary edema. Splashes in the eye should be considered an ophthalmic emergency as it can rapidly penetrate the eye and cause permanent injury.
