Industrial Grade Oxalic Acid Dihydrate (CAS 6153-56-6): Solving Purity and Supply Challenges for Manufacturing
We’ve witnessed countless production delays caused by inconsistent oxalic acid purity—from leather tanneries facing uneven cleaning results to mining operations dealing with unexpected reagent failures. Even 0.5% purity fluctuations can disrupt chemical reactions, and unreliable suppliers often leave factories scrambling for alternatives mid-production. With over a decade in chemical supply, we understand these pains aren’t just about materials—they’re about protecting your production timeline and product quality.
Stable Supply of 99.6% Oxalic Acid Dihydrate for Critical Industrial Processes
Our Industrial Grade Oxalic Acid Dihydrate Powder delivers the consistency your operations demand. Produced in Shandong with a monthly capacity of 6000 tons, we ensure steady availability even for large-scale orders. The 99.6% purity level minimizes impurities that cause副反应, while our hydrolysis production method guarantees batch-to-batch uniformity—critical for maintaining consistent results in leather cleaning and mining applications.
Key Industrial Applications
This versatile compound serves as a vital reagent in multiple industrial sectors. In leather processing, its reducing properties effectively remove lime and stains during tanning, ensuring uniform hide preparation. Mining operations utilize its chelating ability to extract metals from ores, while stone cleaning industries rely on its controlled acidity to dissolve mineral deposits without damaging surfaces. As a dicarboxylic acid, it also functions as a reducing agent in various chemical synthesis processes.
Why Purity and Physical Properties Matter in Industrial Use
The 99.6% purity of our Oxalic Acid Dihydrate directly impacts process efficiency—lower purity grades introduce contaminants that can react with other chemicals, reducing yields and creating hazardous byproducts. Its defined melting point (101-102ºC) ensures predictable behavior in thermal processes, while the 1.772 g/cm³ density allows accurate volumetric dosing. The white powder form ensures easy handling and dissolution, with solubility characteristics (soluble in water/ethanol, insoluble in benzene) that simplify formulation in aqueous and organic systems alike.
Reliable Quality Minimizes Production Risks
Choosing substandard oxalic acid can lead to costly consequences: leather batches with uneven coloring, mining extraction processes with reduced efficiency, or cleaning operations that damage substrates. Our ISO9001-certified production ensures each batch meets strict quality criteria, while SGS testing verifies compliance with international standards. Consistent supply eliminates production line downtime, and our commitment to purity means fewer rejected batches and lower overall production costs—delivering better value than cheaper, lower-quality alternatives.
Stringent Quality Control You Can Verify
Every shipment includes a comprehensive Certificate of Analysis (COA) detailing batch-specific test results, from purity to trace element content. Our quality control process integrates multiple analytical methods, with MSDS documentation providing complete safety handling information. We maintain full production records for 5 years, allowing traceability of any batch. If specifications aren’t met, we offer unconditional replacement—no questions asked. Our technical support team is available to assist with application-specific questions, ensuring you get the most out of your purchase.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA with detailed purity testing and impurity profiles, along with an up-to-date MSDS. For critical applications requiring additional verification, specific batch test data can be requested using your order number, and full analytical reports including method validation details are available upon request.
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.
Simple Order Process for Industrial Buyers
Initiate your order by sending an inquiry with your required quantity and delivery terms (FOB/CIF available). We can arrange sample testing for qualification, with typical sample lead times of 3-5 business days. Once specifications are confirmed, bulk orders ship within 7-10 days from our Qingdao, Tianjin, or Shanghai ports. All shipments include complete customs documentation to ensure smooth import clearance.
