Oxalic Acid CAS 144-62-7: Solving Industrial Purity & Supply Challenges
We've witnessed countless production delays caused by inconsistent oxalic acid purity—from 95% to 99% in the same batch—leading to unexpected副反应 in leather dyeing and marble polishing processes. Worse, unreliable suppliers often fail to meet delivery deadlines, costing manufacturers thousands in downtime. After 10+ years serving industrial clients worldwide, we understand that stable raw material supply isn't just a requirement; it's the foundation of your production efficiency.
A Stable and Reliable Chemical Supply Solution
Our Industrial Grade Oxalic Acid addresses these critical pain points with guaranteed 99.6% purity and consistent batch quality. As a leading chemical export platform with self-operated import/export rights, we've established a robust supply chain supporting 6,000+ global industrial customers. Whether you're processing leather in Italy or polishing marble in the Middle East, our production capacity of 6,000 tons/month ensures your manufacturing line never stalls due to material shortages.
Typical Industrial Applications
This 99.6% purity oxalic acid serves as an essential raw material in multiple industrial processes. In leather dyeing, its reducing properties help achieve uniform color absorption and prevent dye precipitation. For marble polishing, it efficiently removes mineral deposits and stains without damaging stone surfaces. Additionally, it functions as a cleaning agent for stones and a reducing agent in mining operations, all under strict industrial application parameters.
Why Key Specifications Matter
The 99.6% purity level is critical—lower concentrations introduce impurities that cause uneven dye fixation in leather processing and leave residues on marble surfaces. Its medium strong acidity (pKa1=1.25, pKa2=4.27) ensures controlled reaction rates, preventing over-etching of delicate materials. The white powder form guarantees easy dissolution and homogeneous mixing, while strict solubility standards (soluble in water/ethanol, insoluble in benzene) ensure compatibility with various industrial solvents. Each parameter is calibrated to meet ISO9001 standards, directly impacting your end-product quality and process efficiency.
What You Gain With Our Product
Choosing our Ethanedioic Acid for Cleaning Stones means eliminating rework costs from impurity-related defects and reducing production downtime from supply interruptions. Unlike low-quality alternatives that risk non-compliance with European REACH regulations, our product undergoes rigorous SGS testing, ensuring重金属含量 well below international limits. The stable 25kg packaging minimizes material waste during handling, while our ability to fulfill bulk orders within 72 hours from major Chinese ports (Qingdao, Tianjin, Shanghai) reduces inventory holding costs—ultimately improving your production ROI.
Why You Can Trust Us
Every batch undergoes triple testing: initial HPLC analysis for purity, FTIR spectroscopy for structural confirmation, and ICP-MS for heavy metal screening. We provide a detailed COA with each shipment, including specific gravity (1.772 g/cm³), melting point (101-102ºC), and solubility data. If specifications don't match our承诺, we offer full product replacement within 15 days. Our 10+ years of foreign trade experience and long-term partnerships with ISO9001-certified manufacturers ensure consistent quality, while our dedicated technical team provides 24/7 support for application-specific questions.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA with comprehensive test results and a fully compliant MSDS detailing handling precautions. For critical applications requiring historical data, specific batch检测报告 can be retrieved using your order number. Detailed chromatographic and spectroscopic analysis reports are available upon request to support your internal quality control processes.
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 port of destination. We'll provide a quotation under FOB, CIF, or your preferred trade term within 24 hours. For first-time clients, we offer 500g sample testing to verify compatibility with your processes. Once specifications are confirmed, bulk orders can be arranged with flexible payment terms, including letters of credit. All shipments include full customs clearance documentation to streamline your import process.
