Also known as caustic soda or lye, this compound has the molecular formula HNaO and a molecular weight of 39.997 g\/mol. Alliance Chemical distributes this high-purity solid to support chemical processing facilities, laboratories, and manufacturing plants across the United States. Characterized by its rapid solubility in water, this product generates significant heat during dissolution due to its highly exothermic reaction. This chemical serves as a foundational building block in various industrial workflows, including our specialized collection of \u003ca href=\"\/collections\/bases\"\u003ebases\u003c\/a\u003e, serving key roles in chemical synthesis, neutralization reactions, and equipment maintenance protocols.\u003c\/p\u003e\u003cp\u003eAs a premier Texas chemical distributor operating since 1997, Alliance Chemical ensures that our solid sodium hydroxide flakes maintain their physical and chemical integrity from our warehouse to your facility. Our flakes feature low levels of trace impurities, providing a reliable baseline for applications requiring rigorous consistency. We package this material in robust, moisture-resistant containers to prevent deliquescence — the process where the substance absorbs moisture from the air until it dissolves. By purchasing from us, clients secure a dependable source of industrial-grade raw materials. Every order is handled in strict compliance with safety regulations, and a comprehensive Safety Data Sheet (SDS) is provided with every shipment to support your internal risk mitigation plans.\u003c\/p\u003e\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\u003cp\u003eSelecting \u003ca href=\"\/products\/sodium-hydroxide-flakes-acs-grade\"\u003eSodium Hydroxide Flakes ACS Grade\u003c\/a\u003e is critical for applications where minor elemental contaminants would ruin a process or alter analytical measurements. Unlike technical-grade caustic soda, which may contain higher concentrations of heavy metals, chlorides, and carbonates, our ACS Grade material undergoes stringent quality control to ensure maximum purity. Buyers who operate precision chemical manufacturing, standard solution preparation, or complex \u003ca href=\"\/pages\/industries\/chemical-synthesis\"\u003echemical synthesis\u003c\/a\u003e rely on these strict specifications to eliminate variables in their processes.\u003c\/p\u003e\u003cp\u003eUsing an incorrect grade of sodium hydroxide can lead to severe operational failure modes. For instance, trace metallic impurities can poison catalysts in synthetic pathways, leading to incomplete reactions and poor yields. Carbonate contamination can skew titration results and alter the pH profiling of delicate buffer systems. In electrochemical processing, unwanted ions cause baseline drift and compromise the structural integrity of plated layers. Investing in Alliance Chemical's ACS Grade flakes guarantees consistency, safeguarding your equipment, processes, and final outputs against contamination-related disruptions.\u003c\/p\u003e\n\u003cdiv class=\"chemical-profile\" data-source=\"canonical\"\u003e\n\u003ch3\u003eChemical Profile\u003c\/h3\u003e\n\u003cdl\u003e\n\u003cdt\u003eCAS Number\u003c\/dt\u003e\n\u003cdd\u003e1310-73-2\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eHNaO\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e39.997 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003egreater than 266 °F at 760 mmHg (USCG, 1999)\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e604 °F (USCG, 1999)\u003c\/dd\u003e\n\u003cdt\u003eFlash Point\u003c\/dt\u003e\n\u003cdd\u003eNot applicable °C\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e1.5 at 68 °F (USCG, 1999) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003eSodium hydroxide solution appears as a colorless liquid.

According to the product's hazard classifications (H290: May be corrosive to metals; H314: Causes severe skin burns and eye damage), personnel must wear chemical-resistant gloves, a full-face shield, and protective clothing to shield the skin. In environments where dust may be generated, a NIOSH-approved particulate respirator must be worn. We ship this product to professional facilities across the nation, ensuring that a comprehensive Safety Data Sheet (SDS) accompanies each shipment to guide safe unloading and handling.\u003c\/p\u003e\u003ch3\u003eHandling \u0026amp; Storage\u003c\/h3\u003e\u003cp\u003eStore sodium hydroxide flakes in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, organic chemicals, and active metals like aluminum, zinc, and tin, with which it can react to produce flammable hydrogen gas. Keep containers tightly closed, as the flakes are highly hygroscopic and will absorb moisture and carbon dioxide from the air. Ideal storage temperatures should be maintained between 15°C and 30°C. Ensure all storage vessels are constructed of compatible materials such as high-density polyethylene (HDPE) or carbon steel, avoiding copper, brass, and aluminum.\u003c\/p\u003e\u003ch3\u003eOrder \u0026amp; Documentation\u003c\/h3\u003e\u003cp\u003eAlliance Chemical provides the necessary regulatory and technical documentation to support your manufacturing and compliance requirements.
