High Purity Oxalic Acid CAS 144-62-7: Solving Industrial Consistency Challenges
In leather processing, inconsistent oxalic acid purity often leads to uneven dye absorption and material weakening. Mining operations face similar issues—impure batches cause inefficient mineral extraction and equipment corrosion. Our 10+ years serving chemical importers across 50+ countries have shown these problems stem from unstable sourcing, not technical errors.
Stabilized Supply for Critical Industrial Processes
Our Industrial Grade Oxalic Acid delivers 99.6% purity with batch-to-batch variation below 0.2%, eliminating the production disruptions caused by substandard materials. With 6,000 tons monthly capacity and three major loading ports (Qingdao, Tianjin, Shanghai), we ensure 45-day delivery windows even during peak demand seasons.
Core Industrial Applications
This versatile compound serves as a key auxiliary in leather processing—facilitating deliming and bleaching while maintaining collagen structure integrity. In mining, it acts as an effective chelating agent for mineral separation, particularly in rare earth and precious metal extraction. Additionally, its strong reducing properties make it ideal for stone cleaning applications, where controlled dissolution of mineral deposits is critical.
Why Purity and Consistency Matter
The 99.6% purity level minimizes metal ion impurities that cause catalytic side reactions in industrial processes. Its defined melting point (101-102ºC) ensures predictable thermal behavior during leather tanning, while the medium strong acidity profile provides optimal pH control without excessive material degradation. The hydrolytic production method guarantees lower heavy metal content (<0.001%), meeting EU REACH standards for export markets.
Risk Mitigation Through Quality Assurance
Choosing our High Purity Oxalic Acid reduces production rejects by up to 30% compared to lower-grade alternatives. Each batch undergoes HPLC purity testing and heavy metal screening, with results documented in the accompanying COA. Our ISO9001-certified production process ensures compliance with international safety standards, while the UN 3261 classification ensures proper handling throughout the supply chain.
Our Quality Commitment
We implement a triple-inspection protocol: raw material testing upon receipt, in-process sampling during synthesis, and final analysis before packaging. Every shipment includes a batch-specific COA with HPLC chromatograms and MSDS. If technical specifications are not met, we provide full replacement within 15 days. Our technical support team offers application guidance to optimize usage parameters for specific industrial processes.
Certificate of Analysis & Documentation
Each delivery includes a comprehensive COA with purity verification, impurity profiles, and physical property measurements. MSDS documents are provided in multiple languages, detailing safe handling procedures and regulatory compliance information. For critical applications, batch-specific test data can be accessed via our secure client portal using your order reference number.
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
Start by submitting your inquiry with required quantity and delivery timeline. We provide FOB/CIF quotations within 24 hours, followed by sample provision upon request. After sample approval, formalize your order with a letter of credit or deposit. Production typically takes 7-10 days, with full documentation package sent electronically prior to shipment.
