Ammonium Hydroxide 29% Technical Grade

Product Overview

Ammonium Hydroxide 29% Technical Grade is a highly alkaline aqueous solution consisting of ammonia dissolved in water — officially represented by the molecular formula H5NO and a molecular weight of 35.046. This chemical is widely recognized for its intense, pungent, and suffocating odor. As a colorless liquid, it serves as a fundamental building block in industrial synthesis and pH adjustment operations across numerous manufacturing sectors. Alliance Chemical provides this high-concentration basic solution to meet the rigorous demands of commercial and industrial facilities requiring a reliable, consistent alkaline source.

Our technical grade ammonium hydroxide (CAS 1336-21-6) is manufactured to provide a stable 29% concentration, which represents the upper practical limit for stable aqueous ammonia solutions under standard atmospheric conditions. This strong base is widely used in water treatment, chemical manufacturing, and agricultural applications where precise pH control is essential. We maintain strict quality control protocols to ensure that every shipment conforms to established specifications. The product is managed and distributed in accordance with federal and state regulations, emphasizing safety and compliance from our Texas-based distribution center. We offer a full range of industrial bases to support local and national logistics needs.

Why This Grade

Selecting the correct chemical grade and concentration is vital for maintaining process efficiency and preventing operational failures. Technical grade ammonium hydroxide at a 29% concentration provides an optimal balance of high active ingredient content and manageable vapor pressure. Utilizing a lower concentration would require significantly higher solvent volumes, increasing storage footprints and shipping costs. Conversely, using an incorrect or lower grade with higher levels of trace metal impurities can poison catalysts in chemical synthesis or introduce unwanted contaminants in water treatment systems, leading to costly process downtime.

Industrial processes are calibrated for specific molarities, and our 29% solution ensures predictable reaction stoichiometry. If a facility attempts to use a different grade or an unverified dilution, the variations in pH and free ammonia levels can result in incomplete reactions, precipitation of unwanted salts, or dangerous thermal excursions in exothermic neutralization systems. Alliance Chemical's technical grade offers the precise, heavy-duty performance required for large-scale industrial operations where higher purity analytical grades would be cost-prohibitive, yet standard ammonium hydroxide retail solutions are far too weak or contaminated to perform reliably.

Industrial Applications

• Nitrogen source in the production of specialty agricultural fertilizer formulations, helping to optimize crop nutrient profiles.
• pH adjustment and neutralization of acidic waste streams in municipal and industrial water treatment plants to maintain system balance.
• Precursor in the chemical synthesis of organic and inorganic nitrogen-containing compounds, including plastics and synthetic resins.
• Industrial cleaning agent and degreasing formulation component used in metal finishing processes to prepare surfaces for electroplating.
• Neutralizing agent in the pulp and paper industry, assisting in the digestion of wood fibers and controlling process water pH.

Hazmat & Shipping

Ammonium Hydroxide 29% Technical Grade is classified as a hazardous material under DOT regulations due to its corrosive nature. It is officially designated as UN2672, Hazard Class 8, Packing Group III. The proper shipping name is AMMONIA SOLUTIONS. The authoritative signal word is Danger. The product's GHS hazard statements include H314 and H400. As a regulated material, all shipments must comply with strict DOT hazmat transportation guidelines to ensure safe transit from our facilities to your site.

Safe handling of this corrosive solution requires mandatory personal protective equipment (PPE) as outlined in the Safety Data Sheet (SDS). Based on the H314 classification, operators must wear chemical-resistant gloves, a full-face shield or splash goggles, and protective clothing to prevent any skin contact. Respiratory protection may be required in areas with poor ventilation due to the intense, pungent, suffocating odor of emerging ammonia vapors. Comprehensive safety protocols, including eye wash stations and safety showers, must be readily accessible in all storage and transfer areas.

Handling & Storage

Ammonium hydroxide must be stored in a cool, well-ventilated area away from direct sunlight, ideally at temperatures below 25 °C to minimize vapor pressure buildup. Suitable container materials include high-density polyethylene (HDPE), polypropylene, or stainless steel; copper, copper alloys, brass, and galvanized metals are strictly incompatible as they are rapidly corroded by ammonia. Keep containers tightly closed when not in use to prevent the escape of ammonia gas. It is critical to keep this alkaline solution separated from strong acids, halogens, dimethyl sulfate, and oxidizing agents to avoid hazardous chemical reactions.
