Description
Ammonium Hydroxide Product Overview
Ammonium hydroxide (NH4OH, also written as aqueous NH3) is a clear, colorless liquid with a strong, pungent ammonia odor. Common concentrations are 24.5% and 25–30% NH3, and it is much easier to store and handle than anhydrous Ammonia gas.
In addition, power plants and engines use 24.5% aqueous ammonia as the reducing agent in SCR systems that remove nitrogen oxides from flue gas. Similarly, chemical plants use it for pH adjustment and neutralization, rubber producers use it to stabilize natural latex, and hair colorant producers use it as the alkalizing agent in permanent dyes. Electronics producers also use high-purity grades in wafer cleaning solutions.
In addition, it is a common household and industrial cleaning ingredient. Related nitrogen chemicals in our range also include Urea, Ammonium Sulfate and Nitric acid.
Key Applications of Ammonium Hydroxide
Typical uses include, for example:
🏭 DeNOx Systems
Reducing agent in SCR flue gas treatment.
🧪 pH Control
Neutralization as well as pH adjustment.
💇 Hair Colorants
Alkalizing agent in permanent dyes.
🌳 Latex
Stabilizer for natural rubber latex.

⚠️ Safety & Handling: Causes severe skin burns and eye damage, may cause respiratory irritation, and is very toxic to aquatic life; releases ammonia gas. Use good ventilation and also wear chemical-resistant gloves, face protection and respiratory protection where needed. Store in tightly closed containers in a cool place, away from acids, because heat increases ammonia release. Always consult the Safety Data Sheet (SDS), because it contains the full classification and handling instructions.
Frequently Asked Questions
What is the difference between ammonium hydroxide and ammonia?
Ammonia is the pure gas, whereas ammonium hydroxide is its solution in water, which is easier and safer to handle.
Which concentration is used for SCR systems?
Most SCR systems use 24.5% aqueous ammonia, although some designs use other concentrations.
How can I get a price and documents?
Prices depend on quantity, packaging and destination, so please contact us with your required volume. We then send a quotation together with the CoA and SDS.
