Oxalic Acid CAS 144-62-7: Solving Industrial Purity and Supply Challenges
We’ve witnessed countless production delays caused by inconsistent oxalic acid purity—batch variations leading to uneven leather tanning results, ineffective stone cleaning due to low concentration, and unexpected impurities disrupting chemical processes. In our 10+ years serving industrial clients, these issues remain the top frustrations for manufacturers across leather processing and stone maintenance sectors.
Stable Supply of 99.6% Industrial Grade Oxalic Acid
Our Oxalic Acid CAS 144-62-7 addresses these pain points with guaranteed 99.6% purity and consistent batch quality. Backed by a 5000 Tons/Month production capacity and strategic ports in Qingdao, Tianjin, and Shanghai, we ensure timely delivery even for large-scale industrial orders. This stability has made us the trusted partner for over 6,000 global industrial customers seeking reliable chemical raw materials.
Key Industrial Applications
As a versatile dicarboxylic acid, this industrial grade oxalic acid plays a critical role in leather processing—effectively removing lime and mineral deposits during beamhouse operations. Its strong chelating properties also make it ideal for cleaning stones, where it dissolves calcium carbonate deposits without damaging surface integrity. Additionally, it serves as a reducing agent in mining and various chemical synthesis processes, strictly for industrial manufacturing use.
Why 99.6% Purity Matters in Industrial Processes
The 99.6% purity level is not arbitrary—it directly impacts process efficiency and product quality. Higher purity minimizes副反应 by reducing impurities that could interfere with chemical reactions, ensuring cleaner leather tanning and more effective stone cleaning. The controlled solubility profile (soluble in water and ethanol) allows precise concentration adjustments, while the medium strong acidity provides optimal reactivity without excessive corrosiveness. Consistent density (1.772 g/cm³) ensures accurate dosing in automated production lines, critical for maintaining product uniformity.
The Cost of Compromising on Oxalic Acid Quality
Choosing substandard oxalic acid carries hidden costs: rework from uneven leather processing, repeated stone cleaning attempts, and equipment damage from unexpected impurities. Our ISO9001 and SGS-certified production ensures each batch meets strict quality standards, reducing these risks while improving overall process efficiency. The 25kg bag packaging is designed for industrial handling, minimizing waste and simplifying storage logistics—ultimately delivering better value than cheaper, lower-purity alternatives.
Our Quality Assurance Commitment
Every batch of our oxalic acid undergoes rigorous testing via HPLC and titration methods to verify purity and composition. We provide a complete Certificate of Analysis (COA) with each shipment, detailing key parameters like purity, moisture content, and impurity levels. Our production facilities maintain strict quality control from raw material selection through hydrolysis and purification, ensuring batch-to-batch consistency. Should any product fail to meet specifications, we offer unconditional replacement—no questions asked.
Certificate of Analysis & Documentation
All orders include a batch-specific COA and MSDS, providing comprehensive safety and quality data for regulatory compliance. For critical applications, we can arrange additional third-party testing by SGS upon request. Detailed test records are retained for 5 years, allowing traceability for any production audits or quality reviews.
Storage & Handling
- Store in a cool, dry, well-ventilated area, sealed and away from direct sunlight.
- Keep away from incompatible materials, food and feed sources.
- Handle with appropriate personal protective equipment (gloves, goggles, lab coat).
- Follow good industrial hygiene practices. Avoid inhalation and skin contact.
- Refer to MSDS for detailed storage and safety instructions.
Streamlined Order Process for Industrial Buyers
Initiate your order by submitting an inquiry with your required quantity and delivery timeline. We’ll provide a detailed quotation including trade terms (FOB/CIF) and sample availability. Upon sample approval, we’ll finalize the contract and arrange production—typically within 7-10 days for standard orders. All shipments include full customs documentation to ensure smooth import clearance at your destination port.
