Oxalic Acid 99.6% (CAS 144-62-7): Resolving Leather Dye Industry’s Purity & Consistency Challenges
We’ve witnessed countless leather dyeing facilities struggle with batch-to-batch variations in oxalic acid purity—resulting in uneven dye absorption, increased reject rates, and production delays. Inconsistent solubility has forced manufacturers to adjust process parameters constantly, while substandard raw materials have led to equipment corrosion and higher maintenance costs. These challenges aren’t just operational headaches; they directly impact your bottom line and reputation.
A Stable and Reliable Oxalic Acid Supply Solution
Our Oxalic Acid 99.6% (CAS 144-62-7) addresses these critical pain points through rigorous quality control and a decade of chemical manufacturing expertise. With a production capacity of 5,000 tons per month and ISO9001 certification, we ensure consistent purity and performance across every batch. Whether you’re operating a large-scale leather processing plant or a specialized chemical research laboratory, our white powder oxalic acid delivers the stability your processes demand.
Typical Industrial Applications
As a dicarboxylic acid powder, this compound serves as a vital reducing agent in leather dyeing processes, facilitating color fixation and improving dye penetration. Beyond the leather industry, it finds applications in mining operations for mineral processing, stone cleaning for architectural restoration, and various industrial cleaning processes. Its properties make it particularly valuable in applications requiring controlled acidity and reducing capabilities, always within industrial and laboratory contexts.
Why Key Specifications Matter
The 99.6% purity level of our oxalic acid minimizes impurities that could interfere with dye reactions, ensuring consistent color results and reducing byproduct formation. Its defined melting point (101-102ºC) allows for precise process temperature control, critical in leather treatment stages where heat affects dye uptake. The medium strong acidity provides optimal pH adjustment without causing excessive material degradation, while the white powder form ensures uniform mixing and solubility—eliminating the clumping issues common with lower-grade products.
What You Gain With Our ISO9001 Oxalic Acid
Choosing our ISO9001-certified oxalic acid means investing in process reliability and cost efficiency. Superior purity reduces raw material waste by up to 15% compared to lower-grade alternatives, while consistent batch quality eliminates costly reworks and production downtime. Our strict quality control ensures compliance with international industrial standards, simplifying import procedures for your global operations. With stable pricing and guaranteed supply, you can avoid the market volatility that often disrupts production schedules.
Why You Can Trust Us
Every batch of our oxalic acid undergoes comprehensive testing, including HPLC analysis for purity verification and moisture content assessment. We provide a complete Certificate of Analysis (COA) with each shipment, detailing key parameters like assay value, heavy metal content, and pH. Our production facilities in Shandong adhere to strict environmental and safety protocols, supported by SGS audits. With 10+ years of experience serving industrial customers worldwide, we offer responsive technical support and flexible logistics solutions from major Chinese ports (Qingdao, Tianjin, Shanghai).
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA and MSDS, containing detailed safety, handling, and storage information. For critical applications requiring additional verification, we can provide full spectral analysis (IR, NMR) upon request. All documentation complies with international trade requirements, facilitating customs clearance in your target market.
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 order by submitting an inquiry with your required quantity and delivery location. We’ll provide a detailed quotation including trade terms (FOB/CIF) and estimated lead time. For first-time customers, we recommend requesting a sample for qualification testing. Once specifications are confirmed, we’ll arrange production, inspection, and shipment with full documentation support to ensure a smooth customs clearance process.
