Product Overview
Alliance Chemical provides high-purity Nitric Acid 65% ACS Grade to meet the strict analytical testing and processing requirements of diverse industries. This high-purity solution, with the chemical formula HNO3 and molecular weight 63.013, represents an essential strong acid utilized across research laboratories, electronic manufacturing, and metal fabrication. As a premier Texas chemical supplier, we ensure this material is managed under strict quality controls to maintain its stability and concentration. This product is designed strictly for industrial use and professional laboratory applications, providing the reliability required for precise chemical processes.
Our Nitric Acid 65% ACS Grade is a clear, pale yellow to reddish brown liquid that displays strong oxidizing properties and a characteristic choking odor. It is highly miscible in water, facilitating accurate dilutions for specific laboratory titrations and chemical synthesis workflows. Since this product is highly corrosive to both metals and organic tissue, handling requires strict adherence to safety protocols. We distribute this acid in multiple volume configurations, from one-liter bottles to bulk 55-gallon stainless steel drums, to accommodate both bench-scale experimentation and larger industrial procedures.
Why This Grade
Selecting the appropriate chemical grade is vital for maintaining the integrity of experimental data and chemical manufacturing outcomes. ACS Grade specifications are set by the American Chemical Society, ensuring that the concentration of trace impurities like heavy metals, sulfates, and chlorides remains below extremely low thresholds. When performing analytical testing or high-tech manufacturing, utilizing a lower-grade acid can introduce unwanted metal ions, which act as catalysts for unintended side reactions or ruin delicate substrates. For instance, in semiconductor wafer processing, even part-per-million levels of contamination will cause component failure and disrupt manufacturing yields.
The 65% concentration is the standard bench reagent strength, optimized for stability and reactivity. Lower concentrations may lack the necessary thermodynamic power to drive oxidation reactions, while higher concentrations (such as fuming nitric acid) present severe safety risks and spontaneous decomposition challenges. Using an incorrect concentration or an industrial-grade alternative can lead to incomplete digestion of analytical samples, leading to skewed calibration curves and invalid test results. Alliance Chemical ensures that our 65% ACS Grade material remains within strict specifications to prevent these costly process failures.

Hazmat & Shipping
Nitric Acid 65% ACS Grade is classified as a hazardous material due to its strong corrosive and oxidizing properties. Under Department of Transportation guidelines, this product is designated as UN2031, Hazard Class 8, Packing Group II. The proper shipping name is Nitric acid, other than red fuming, with at least 65 percent, but not more than 70 percent nitric acid. This material carries the Signal Word Danger. Because it is a strong oxidizer, it can accelerate the combustion of surrounding materials, requiring isolated shipping configurations. All shipments are packaged and dispatched according to strict DOT regulations to guarantee safe arrival at your facility.
The safety of operational personnel is paramount when handling this substance. In accordance with the GHS classifications H314 (Causes severe skin burns and eye damage) and H330 (Fatal if inhaled), specific personal protective equipment (PPE) is mandatory. Handlers must wear chemical-resistant gloves, a full face shield, protective acid-resistant clothing, and work under a certified fume hood. If ventilation is insufficient, appropriate respiratory protection matching hazard code H330 must be utilized. Alliance Chemical provides a comprehensive Safety Data Sheet (SDS) provided with every order to assist your safety compliance officer in establishing safe handling protocols.
Handling & Storage
Safe storage of Nitric Acid 65% ACS Grade requires dedicated, cool, and dry facilities away from direct sunlight and heat sources, ideally maintained at temperatures between 50°F and 85°F. This acid is highly incompatible with organic compounds, flammable solvents, reducing agents, and active metals, as contact can prompt rapid, exothermic reactions. Storage containers must be made of compatible materials, such as glass, fluorinated polymers (PTFE), or specialized stainless steel alloys. Keep containers tightly sealed to prevent the accumulation of hazardous vapors, and store them within a secondary containment system to safely manage any potential leaks.
