As an anhydrous equivalent or dihydrate-derived crystalline solid, it serves as a critical reagent in various analytical, industrial, and laboratory processes. Alliance Chemical distributes this high-purity chemical to facilities across North America — ensuring that it meets strict quality standards. This product is key for facilities that require exact chemical compositions for their manufacturing operations. It is widely recognized for its strong chelating and reducing properties in specialized industrial applications.\u003c\/p\u003e\u003cp\u003eOur Oxalic Acid ACS Grade is manufactured to ensure low trace metal impurities, making it highly reliable for demanding scientific operations. This white crystalline solid exhibits excellent solubility in water and other solvents under controlled conditions. Industrially, it is used in anodizing, metal treatment, textile processing, and chemical synthesis. Choosing Alliance Chemical means you are receiving a product backed by our decades of distribution expertise. We provide consistent quality control to meet your operational requirements, whether you operate a testing laboratory or a large-scale manufacturing plant.\u003c\/p\u003e\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\u003cp\u003eThe ACS Grade designation indicates that this material complies with the strict specifications of the American Chemical Society. This standard is necessary for applications where even minor trace metal impurities can disrupt chemical reactions or contaminate sensitive substrates. Using a lower commercial grade instead of ACS Grade can introduce unwanted contaminants, such as heavy metals or iron, which interfere with complexation or oxidation-reduction steps. For high-precision testing and synthesis, this high purity is essential to prevent secondary reactions that skew analytical results or ruin valuable chemical batches.\u003c\/p\u003e\u003cp\u003eWhen executing precise surface treatments, such as aluminum anodizing or textile processing, impurities in lower-grade oxalic acid can cause pitting, discoloration, or inconsistent bonding. Choosing this exact grade avoids these common failure modes, ensuring that chemical behaviors remain predictable across all batches. Facilities relying on consistent pH control or exact reducing action require this high concentration of pure C2H2O4. Alliance Chemical supplies this ACS Grade to eliminate process variability and to maintain the integrity of your technical operations and final outputs.\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\u003e144-62-7\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eC2H2O4\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e90.03 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003eSublimes (NIOSH, 2024) °C\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e372 °F (Decomposes) (NTP, 1992)\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e1.9 at 59 °F (USCG, 1999) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003eOxalic acid is an odorless white solid.
