Oxalic Acid 99.6% (CAS 144-62-7): Overcoming Industrial Purity & Supply Challenges
For over a decade in chemical manufacturing, we've witnessed how inconsistent Oxalic Acid purity disrupts leather processing lines—causing uneven cleaning results and unexpected equipment corrosion. Researchers repeatedly report batch-to-batch variations that invalidate months of material testing, while procurement teams struggle with suppliers who fail to meet delivery timelines during peak production seasons.
A Stable and Reliable Chemical Supply Solution
Our Industrial Grade Oxalic Acid (CAS 144-62-7) addresses these critical pain points through a controlled hydrolysis production process that ensures 99.6% purity with minimal impurities. As a leading chemical export platform with 10+ years of experience serving 6,000+ industrial customers worldwide, we maintain a monthly production capacity of 5,000 tons to guarantee consistent supply even for large-scale leather cleaning operations and specialized research projects.
Typical Industrial Applications
This Dicarboxylic Acid for Cleaning is widely utilized in leather processing for efficient decontamination and pH adjustment, acting as a powerful reducing agent in metal surface treatment, and serving as a key raw material in mining operations for mineral processing. Its high solubility in water and ethanol makes it suitable for formulating industrial cleaning solutions, while its stable chemical properties ensure compatibility with various manufacturing processes.
Why Key Specifications Matter
The 99.6% purity level of our Oxalic Acid minimizes副反应 during leather cleaning, reducing the risk of surface discoloration compared to lower-grade alternatives. Its precisely controlled melting point (101-102ºC) ensures consistent dissolution behavior in industrial baths, while the medium strong acidity provides optimal reactivity without excessive material degradation. The low impurity profile, validated by ISO9001 and SGS certifications, meets strict export standards for European and American markets, eliminating customs clearance delays caused by non-compliant raw materials.
What You Gain With Our Product
Choosing our Ethanedioic Acid means reducing production downtime by 15-20% through batch consistency, lowering reject rates in leather processing, and avoiding costly rework from substandard chemicals. Unlike unreliable suppliers offering inconsistent purity, our strict quality control ensures every 25kg bag meets identical specifications, directly translating to predictable manufacturing costs and stable product quality. Compliance with international standards (UN No. 3261) also mitigates logistics risks associated with hazardous material transportation.
Why You Can Trust Us
Our quality assurance process includes triple-stage HPLC testing for purity verification, moisture content analysis to prevent clumping, and heavy metal screening to meet REACH requirements. Each shipment includes a batch-specific COA (Certificate of Analysis) with detailed test results, while MSDS documents provide comprehensive safety handling instructions. We offer a 30-day quality guarantee—if specifications don't match our commitment, we arrange full replacement or refund without additional costs. Our production base in Shandong Province, China, operates 24/7 to ensure continuous supply, supported by multiple loading ports (Qingdao, Tianjin, Shanghai) for flexible logistics planning.
Certificate of Analysis & Documentation
Every order is accompanied by a batch-specific Certificate of Analysis containing actual test data for key parameters including purity, moisture, and impurity levels. MSDS documents are provided in compliance with GHS standards, detailing safe handling, storage, and emergency procedures. For critical applications, we can arrange third-party SGS testing at customer request, with results available within 5 working days of sample submission.
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 sending an inquiry with your required quantity and delivery terms (FOB/CIF available). We provide free sample evaluation (up to 500g) for qualified industrial customers to verify compatibility with your processes. Upon sample approval, formalize your order with a foreign trade contract, and we'll arrange production, commodity inspection, and customs declaration. Full documentation (invoice, packing list, COA, MSDS) is provided with each shipment to facilitate smooth customs clearance.
