Ammonium Hydroxide 29% ACS Grade

Product Overview

Ammonium Hydroxide 29% ACS Grade is a clear, colorless aqueous solution of ammonia in water, representing a critical alkaline reagent for modern industrial and scientific applications. Operating as a reliable alkaline base, this solution is manufactured to meet the strict analytical standards of the American Chemical Society (ACS). The material provides high purity with minimal trace metal contamination, ensuring that experimental results and industrial processes remain highly reproducible across critical environments. Alliance Chemical acts as a direct distributor of this high-grade chemical, which you can browse under our bases collection, to laboratories, research institutions, and manufacturing facilities across North America, ensuring the product is packaged, handled, and delivered in strict compliance with all relevant DOT safety regulations.

As an aqueous solution, Ammonium Hydroxide is frequently utilized in pH control, chemical synthesis, and metal surface preparation. When handling this volatile liquid, it is critical to recognize that it constantly releases pungent ammonia vapor, which presents distinct handling requirements. The solution is inherently highly alkaline and acts as a strong corrosive agent, necessitating specialized containment systems and robust physical engineering controls. This concentration of 29% represents the near-saturation point of ammonia in water at ambient temperatures, meaning that the solution must be stored under controlled conditions to prevent excessive pressure buildup within the storage vessels. Alliance Chemical ensures that each container is filled and sealed under controlled conditions to maintain the correct concentration and chemical integrity.

Why This Grade

Selecting the ACS Grade with a 29% concentration is essential for applications where trace impurities, such as heavy metals, chloride, or sulfate ions, could interfere with chemical reactions or analysis. Industrial chemical synthesis, analytical testing, and delicate manufacturing processes require consistent reagent profiles to ensure predictable reaction kinetics. Using a lower technical grade instead of the verified ACS Grade can introduce iron, lead, or copper contamination, which catalyzes undesirable side reactions, leading to failed batches and altered chemical structures.

Furthermore, opting for a lower concentration of ammonium hydroxide means purchasing and transporting unnecessary water, which alters the stoichiometry of chemical mixtures and increases shipping costs. If an operator mistakenly introduces an unverified concentration or a grade containing higher trace elements, it can lead to complete process failure, catalyst poisoning in synthesis loops, or corrupted analytical baselines in laboratory tests. Consistently sourcing our ACS Grade guarantees that your operations maintain a precise and reliable baseline, protecting expensive laboratory instruments and production machinery from unwanted chemical scaling and corrosion.

Industrial Applications

• Chemical Synthesis and Reagent Manufacturing: Used as a fundamental precursor and neutralizing agent in the production of ammonium salts, organic compounds, and agricultural nitrogen formulations.
• Metal Surface Etching and Treatment: Employed in the metallurgical industry to clean, etch, and finish metals like copper and aluminum, preparing surfaces for subsequent coating or plating operations.
• Laboratory Analysis and Chromatography: Serves as a standard buffer and pH adjuster in HPLC, analytical titrations, and scientific research requiring strict ACS-level purity.
• Electronics and Semiconductor Cleaning: Utilized as a high-purity cleaning agent in the manufacturing of silicon wafers, helping remove microscopic particulate contamination without leaving metallic residues.
• Water Treatment and Boiler Maintenance: Applied to control pH levels and prevent corrosion in high-pressure steam boiler systems and industrial cooling towers by neutralizing acidic components.

Hazmat & Shipping

Ammonium Hydroxide 29% ACS Grade is classified as a regulated hazardous material due to its highly corrosive nature and potential to release toxic vapors. According to hazardous materials regulations, this product is designated as UN2672, Hazard Class 8, Packing Group III, and carries the proper shipping name Ammonia solution. The assigned signal word is DANGER. The chemical classification indicates that it presents physical hazards, particularly severe skin burns and eye damage, and environmental hazards as it is highly toxic to aquatic life. Consequently, transportation is subject to strict DOT requirements, and Alliance Chemical ships this product in compliant packaging through registered hazardous materials carriers.

When handling and receiving this substance, personnel must wear appropriate personal protective equipment (PPE) to mitigate risks associated with the GHS H-codes. The hazardous statements H314 and H400 necessitate the use of chemical splash goggles, full face shields, heavy-duty neoprene or nitrile gloves, and chemical-resistant aprons or suits. Adequate local exhaust ventilation or vapor respirators must be utilized to protect operators from inhaling the intense, pungent, and suffocating ammonia vapors that naturally arise from the solution. A Safety Data Sheet (SDS) is provided with every order to detail comprehensive first aid measures, spill containment protocols, and specific compliance guidelines.

Handling & Storage

To maintain product quality and safety, Ammonium Hydroxide 29% ACS Grade must be stored in a cool, well-ventilated location away from direct sunlight and sources of heat. The ideal storage temperature should be kept below 25 °C to minimize vapor pressure buildup, which can reach 2160 mm Hg at 25 °C. Compatible container materials include high-density polyethylene (HDPE), polypropylene, and specific lined carbon steels. Avoid contact with incompatible materials such as copper, copper alloys, brass, galvanized metals, strong acids, halogens, and heavy metals, as contact can result in violent reactions or the formation of explosive compounds. Regular monitoring of storage vessels for integrity is highly recommended.
