Oxalic Acid 99.6% CAS 144-62-7: Overcoming Industrial Purity and Supply Challenges
For over a decade in chemical manufacturing, we’ve witnessed how inconsistent Oxalic Acid purity disrupts leather tanning processes—causing uneven dye absorption and product rejections. Laboratory researchers repeatedly report batch-to-batch variations that make experimental results irreproducible, while procurement teams struggle with suppliers who fail to meet delivery deadlines during peak production seasons.
A Stable and Reliable Chemical Supply Solution
Our Oxalic Acid 99.6% CAS 144-62-7 addresses these critical pain points through stringent manufacturing controls and a supply chain built for industrial reliability. With self-operated import-export rights and 5000 Tons/Month production capacity, we’ve established long-term partnerships with over 6,000 industrial customers across 50+ countries, ensuring consistent availability even during market fluctuations.
Typical Industrial Applications
This White Powder Oxalic Acid serves as a cornerstone in the Leather Industry for deliming and bleaching processes, where its precise acidity ensures optimal collagen fiber preparation. In the Dyeing Industry, it functions as a reducing agent that stabilizes colorants, preventing oxidation and ensuring vivid, long-lasting hues. Additional industrial uses include mineral processing, stone cleaning, and metal surface treatment—all strictly within manufacturing and research contexts.
Why Key Specifications Matter
The 99.6% purity level of our Oxalic Acid minimizes impurities that cause side reactions in leather processing, reducing material waste by up to 15% in tanning operations. Its medium strong acidity (pKa1=1.27, pKa2=4.27) provides controlled pH adjustment critical for dye fixation, while the 101-102ºC melting point ensures thermal stability during industrial mixing processes. The stringent solubility profile—soluble in water and ethanol yet insoluble in benzene—allows for precise solvent-based applications without cross-contamination risks. Each batch maintains these specifications through ISO9001-certified quality control, directly impacting production efficiency and end-product consistency.
What You Gain With Our Product
Choosing our Ethanedioic Acid for Dyeing and leather applications delivers quantifiable benefits: reduced production downtime from reliable supply, lower rejection rates due to consistent purity, and compliance with international export standards through SGS-certified quality. Unlike low-grade alternatives that introduce heavy metal impurities or variable concentrations, our industrial-grade Oxalic Acid ensures process repeatability that translates to predictable costs and higher profit margins. With production capacity supporting both bulk orders and research quantities, we eliminate the common trade-off between quality and scalability.
Why You Can Trust Us
Our quality assurance begins with raw material screening and continues through every production stage with in-line HPLC and titration analysis. Each shipment includes a batch-specific COA detailing purity, moisture content, and heavy metal levels, while MSDS documentation ensures safe handling. Our Shandong-based manufacturing facility operates under ISO9001 standards, with production processes audited annually by third-party inspectors. We stand behind our product with a 30-day quality guarantee—if specifications don’t match our COA, we arrange replacement or full refund. With 10+ years in chemical export and direct access to major ports (Qingdao, Tianjin, Shanghai), we provide transparent supply chain visibility from production to delivery.
Certificate of Analysis & Documentation
Every order includes a comprehensive Certificate of Analysis with batch-specific test results for key parameters including purity, water content, and insoluble matter. Material Safety Data Sheets (MSDS) provide detailed handling instructions, storage requirements, and emergency protocols. For critical applications, customers may request additional testing documentation including specific impurity profiles or stability studies, with results available within 48 hours of 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.
How to Place Your Order
Initiate your purchase by submitting an inquiry with your required quantity and delivery timeline. Our technical team can provide sample evaluation (500g-1kg) for process validation before full-scale ordering. Once specifications are confirmed, we issue a proforma invoice with clear trade terms (FOB/CIF options available). Production typically takes 3-5 business days for standard orders, with tracking provided from factory to port. All shipments include full customs documentation for smooth import clearance.
