Product Overview
Alliance Chemical provides high-quality Sulfuric Acid 70% (CAS 7664-93-9) to meet demanding industrial requirements across various chemical and manufacturing sectors. As a dense, colorless, oily liquid, sulfuric acid is a highly corrosive mineral acid with a molecular formula of H2O4S — molecular weight 98.08 g/mol. This concentrated solution is widely used as an industrial catalyst, an electrolyte, and a chemical intermediate, offering consistent reactivity and high chemical stability. Our rigorous quality control standards ensure that every batch of this dense mineral acid meets rigorous purity thresholds, ensuring predictable performance in sensitive industrial processes.
Sulfuric acid is highly soluble in water with a significant release of heat, requiring careful handling and precise dilution procedures in industrial environments. This chemical is highly corrosive to metals and organic tissues, requiring strict adherence to safety protocols during transport, storage, and application. At a concentration of 70%, it serves as a highly effective agent for pH adjustment, metal cleaning, and chemical synthesis. We distribute acids and other specialty chemicals in multiple packaging options to suit operations of all scales, ensuring a reliable supply of this essential industrial reagent for businesses across North America.
Why This Grade
Selecting the correct concentration of sulfuric acid is critical for ensuring process efficiency and protecting industrial equipment from premature failure. Our Sulfuric Acid 70% is formulated specifically for applications where higher concentrations, such as 93% or 98%, would be overly aggressive or generate excessive heat during dilution. Using an incorrect concentration can lead to severe process failures, such as rapid equipment corrosion, runaway exothermic reactions, or incomplete chemical transformations. By choosing a pre-diluted 70% concentration, operators can minimize the safety hazards associated with on-site dilution while maintaining the necessary acidic strength for specialized industrial workflows.
For example, in metal processing and pickling operations, an overly concentrated acid can over-etch or char the metal surface, while a concentration below 70% may fail to remove oxide scales effectively. In chemical synthesis, a precise 70% concentration ensures optimal reaction kinetics without degrading sensitive raw materials or catalysts. Relying on inconsistent or improper grades can introduce unwanted impurities, leading to batch rejection and costly downtime. We provide a Certificate of Analysis (COA) with our batches to verify that the concentration is maintained precisely at 70%, ensuring that your industrial systems operate under optimal, standardized conditions.

Hazmat & Shipping
Sulfuric Acid 70% is a highly regulated hazardous material due to its highly corrosive properties. Under Department of Transportation (DOT) regulations, this product is classified as UN1830, Hazard Class 8 (Corrosive), Packing Group II. The proper shipping name for this material is Sulfuric acid. The mandatory signal word associated with this product is Danger. Due to these hazards, all shipments must comply with strict federal safety standards and are handled by licensed hazmat carriers. Our packaging is designed and certified to prevent leaks or spills during transport, ensuring the safe arrival of your order at your facility.
Safety is paramount when handling materials associated with GHS hazard statement H314, which indicates that the chemical causes severe skin burns and eye damage. Operators must wear appropriate personal protective equipment (PPE) to minimize exposure risks. This includes heavy-duty chemical-resistant gloves, a full-face shield, protective aprons, and vapor respirators as outlined in the safety documentation. Refer to the SDS for the full suite of precautions including P260, P264, P280, P301+P330+P331, P302+P361+P354, P304+P340, P305+P354+P338, P316, P321, P363, P405, and P501. A comprehensive Safety Data Sheet (SDS) is provided with every order to ensure your staff has access to critical safety, handling, and disposal protocols.
Handling & Storage
When storing Sulfuric Acid 70%, it is critical to use compatible containers such as high-density polyethylene (HDPE), fluoropolymer plastics, or specially lined steel tanks. This corrosive liquid must be stored in a cool, dry, well-ventilated area, ideally within a temperature range of 50 °F to 104 °F to prevent freezing or thermal degradation. Keep the container tightly closed and separate from incompatible substances, including strong bases, organic materials, water, active metals, and combustible compounds, as contact can trigger violent exothermic reactions. Implementing robust secondary containment systems is essential to manage any accidental leaks or structural failures.
