Chemical Profile

Product Overview

Ammonium Hydroxide 29% ACS Grade is a high-purity solution of ammonia (NH3) dissolved in water, also commonly referred to as Aqueous Ammonia or Ammonia Solution. This product is manufactured to meet or exceed strict ACS Reagent Grade specifications, ensuring a consistent assay of approximately 29% w/w NH3. It features a low impurity profile with tightly controlled limits on residue, heavy metals, and chlorides.

Industrial buyers and laboratory professionals rely on this grade for applications requiring precise stoichiometry and minimal interference. It serves as a strong alkaline reagent for pH neutralization, a precursor in chemical synthesis, and a solvent in various hydrometallurgical processes. The 29% concentration provides a high buffering capacity, making it efficient for water treatment protocols and manufacturing formulations where high alkalinity is required.

Metal Finishing: utilized in cleaning and degreasing formulations for metal surfaces (aluminum, copper) and electronics manufacturing.
Cleaning Agent: Industrial strength cleaner for glass and equipment degreasing where no residue is desired.

Safety & Handling

Ammonium Hydroxide is a corrosive alkaline liquid and emits pungent ammonia vapors. It must be handled with appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves, splash goggles, and face shields. Ensure use in a well-ventilated area or fume hood to avoid inhalation of vapors. Store in a cool, dry place, away from incompatible materials such as strong acids, halogens, and heavy metals. Keep containers tightly closed to prevent ammonia loss through evaporation.
