Acetic Acid Glacial ACS Grade

Product Overview

Acetic Acid Glacial ACS Grade represents an exceptionally pure, high-quality concentrated form of acetic acid, carefully processed and verified to meet the strict standards established by the American Chemical Society. This chemical is designated by the CAS registry number 64-19-7 and has the chemical formula C2H4O2, possessing a molecular weight of 60.05. As a Texas chemical supplier operating since 1997, Alliance Chemical ensures this high-purity solvent is made available for critical laboratory, analytical, and demanding industrial applications that require minimal impurities and maximum consistency. The term "glacial" refers to the anhydrous nature of this organic acid, which solidifies or crystallizes into ice-like structures at temperatures just below room temperature, specifically around 61.9 °F. This pure liquid exhibits a sharp, pungent odor that is highly characteristic of concentrated vinegar, and it presents as a clear, colorless liquid. Because of its absolute concentration, it is widely utilized as a solvent for organic synthesis, an analytical reagent in wet chemistry, and a fundamental building block in various manufacturing processes.

When sourcing chemicals for sensitive operations, choosing the right supplier and correct grade of acid is paramount to ensuring process stability. Our Acetic Acid Glacial ACS Grade is thoroughly analyzed to maintain strict trace-metal limits and low water percentages, establishing a baseline of performance that standard technical or industrial-grade solutions cannot achieve. This product is packaged under rigorous quality control standards in a variety of container options, from one-quart bottles to larger case volumes, helping laboratories and facilities manage their inventory based on precise usage requirements. Our technical sales team is fully prepared to provide documentation for each batch to guarantee compliance and support your quality assurance program. Alliance Chemical serves as a reliable link in your supply chain, delivering pure reagents designed to meet analytical criteria without unnecessary delay or compromise. We provide a Safety Data Sheet (SDS) with every order, ensuring your operating procedures align with standard hazmat regulations and handling protocols.

Why This Grade

Selecting the ACS Grade of glacial acetic acid is essential when your processes demand precise analytical control, where even trace contaminants can interfere with chemical reactions or analysis. Lower grades of acetic acid often contain higher levels of impurities such as heavy metals, iron, chlorides, and sulfates, as well as a greater percentage of water content. In quantitative analysis, spectrophotometry, or delicate chemical synthesis, these impurities act as catalysts for unwanted side reactions, distorting experimental outcomes or contaminating final products. For instance, in polymer manufacturing or organic synthesis, trace moisture or metal ions can deactivate catalysts, resulting in incomplete reactions, reduced yields, or structurally compromised materials. Utilizing our ACS Grade ensures that your baseline parameters remain consistent from batch to batch, eliminating variables that could derail research or manufacturing workflows.

The failure modes associated with using non-ACS grades are particularly critical in applications like electronics manufacturing, battery testing, or fine chemical synthesis. In these fields, minor deviations in electrical conductivity, trace-metal contamination, or solvent purity can lead to catastrophic failure of the final component. If a technician uses a technical-grade acid instead of ACS Grade, the presence of trace metallic impurities might cause unexpected precipitation or side-reactions during esterification, forming unwanted byproducts that are difficult to separate. Furthermore, variations in water concentration can significantly affect the solubility of solutes, leading to inaccurate standard preparations or poor-quality crystallization processes. By choosing our ACS Grade, you mitigate these operational risks and protect your equipment from the corrosion and fouling that inferior, unpredictable chemical grades often introduce to sensitive fluid systems.

Industrial Applications

• Chemical Synthesis and Acetate Production: Used as a primary reactant in the synthesis of acetate esters, vinyl acetate monomer, and cellulose acetate polymers.
• Analytical Laboratory Reagent: Serving as an essential solvent and titrant in analytical chemistry laboratories for non-aqueous titrations and standard preparation workflows.
• Petroleum and Oilfield Production: Applied in oil and gas extraction processes to adjust fluid pH, prevent scale formation, and stimulate carbonate formations.
• Textile and Dyeing Processes: Employed as a neutralizing agent, pH adjuster, and dye fixative in industrial textile manufacturing to ensure consistent color fastness.
• Industrial Solvent and Descaling: Utilized in specialized cleaning systems to remove scale, metal oxides, and mineral deposits from industrial piping and boilers.

Hazmat & Shipping

Acetic Acid Glacial ACS Grade is classified as a regulated hazardous material due to its corrosive and flammable properties. For transport, this chemical is designated under the United Nations shipping regulations as UN2789, with a primary hazard class of 8 (Corrosive). The subsidiary hazard class is not applicable for this transport classification. It is assigned to Packing Group II, which indicates a medium danger level requiring robust, certified packaging. The proper shipping name under DOT regulations is Acetic acid, glacial. The assigned signal word is Danger, reflecting the serious risks associated with contact and inhalation of concentrated vapors. This material presents a dual hazard: it is highly corrosive to metals and human tissue while also maintaining a flash point of 104 °F, making it a flammable liquid under certain conditions.

Proper personal protective equipment (PPE) is mandatory when handling this material to mitigate risks associated with its GHS classifications, which include hazard statements H226 (Flammable liquid and vapor) and H314 (Causes severe skin burns and eye damage). In accordance with precautionary statement P280, personnel must wear chemical-resistant gloves, protective suits, splash-resistant goggles, and a full face shield. When handling this substance in poorly ventilated spaces, appropriate respiratory protection is required to prevent inhalation of the pungent, irritating vapors. We provide a Safety Data Sheet (SDS) with every order to ensure that your facility is fully equipped with the necessary safety protocols. All shipments are packaged and shipped in strict compliance with federal regulations to ensure safe transit from our facilities to your delivery location.

Handling & Storage

To prevent crystallization, Acetic Acid Glacial ACS Grade should be stored in a climate-controlled environment kept above its freezing point of 61.9 °F, ideally between 65 °F and 85 °F. It must be kept away from open flames, hot surfaces, and other ignition sources due to its flammable properties. Suitable container materials include high-density polyethylene (HDPE), glass, and stainless steel, whereas mild steel, copper, and bronze are highly incompatible and will suffer rapid corrosion. This acid is highly incompatible with strong oxidizing agents, strong bases, and active metals, as contact can trigger highly exothermic reactions or generate flammable hydrogen gas.
