Oxalic Acid 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 and cleaning stone treatments—causing uneven dye absorption, surface etching inconsistencies, and production delays. Many industrial clients struggle with suppliers who compromise on key parameters, leading to batch-to-batch variations that derail quality control and increase operational costs.
A Stable and Reliable Industrial Oxalic Acid Supply Solution
Our Industrial Grade Oxalic Acid (CAS 144-62-7) with 99.6% purity addresses these critical pain points through rigorous manufacturing standards. As a leading chemical export platform with self-operated import-export rights, we've established a supply chain that ensures consistent quality across 6,000+ global industrial customers, delivering reliable material for leather processing, stone cleaning, and other industrial applications.
Typical Industrial Applications
Ethanedioic Acid Industrial Grade serves as a vital raw material in multiple sectors: in leather production, it acts as a cleaning and bleaching agent to remove lime deposits and prepare hides for tanning; in stone cleaning, its chelating properties effectively dissolve mineral stains and rust from marble, granite, and concrete surfaces. Additionally, it functions as a reducing agent in mining operations and metal processing industries, where controlled reactivity is essential for efficient extraction processes.
Why Key Specifications Matter for Industrial Processes
The 99.6% purity of our Oxalic Acid minimizes impurities that cause unwanted side reactions in leather treatment—such as calcium oxalate precipitates that damage hides. Its defined melting point (101-102ºC) ensures consistent dissolution behavior in industrial baths, while the medium strong acidity provides optimal pH control without over-etching delicate stone surfaces. The white powder form guarantees uniform mixing in formulations, preventing clogging in automated production lines compared to granular alternatives. Most importantly, strict heavy metal control (verified by SGS testing) meets EU and North American export standards, eliminating customs clearance delays.
What You Gain With Our 99.6% Purity Oxalic Acid
Choosing our White Powder Oxalic Acid reduces production reject rates by up to 30% compared to lower purity alternatives, directly impacting your bottom line. The ISO9001-certified manufacturing process ensures each batch meets identical specifications, eliminating the need for rework or recipe adjustments between orders. Our 6000 Tons/Month production capacity guarantees stable supply even during peak demand periods, avoiding the production halts that occur with smaller suppliers. Unlike raw materials with hidden impurities, our fully documented quality control provides traceability from synthesis to delivery, supporting your regulatory compliance efforts.
Why You Can Trust Our Oxalic Acid Supply
Every batch of our Oxalic Acid undergoes comprehensive testing using HPLC and titration methods to verify purity, with results documented in a Certificate of Analysis (COA) provided with each shipment. Our manufacturing facility maintains full traceability of raw materials, and we offer third-party testing through SGS upon request. If any parameter fails to meet the specified 99.6% purity standard, we provide unconditional replacement or full refund—no questions asked. Our technical support team, with average 8+ years of industry experience, is available to assist with application-specific questions, from optimal dissolution rates to storage stability.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA detailing purity, moisture content, heavy metal levels, and other critical parameters. MSDS documents are provided in multiple languages, including English, Spanish, and German, to support your safety compliance requirements. For qualifying orders, we can arrange for additional third-party certification from accredited laboratories. Detailed chromatographic data and impurity profiles are available upon request for research institutions and quality-critical applications.
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 Oxalic Acid Order
Initiate your order by submitting an inquiry with your required quantity and delivery timeline. We provide quotations under FOB, CIF, and other trade terms to suit your logistics preferences. For first-time clients, we offer small sample quantities for qualification testing before full-scale orders. Upon confirmation, we arrange production, commodity inspection, and customs declaration, with delivery from Qingdao, Tianjin, or Shanghai ports as needed. All shipments include complete documentation for customs clearance, ensuring smooth import processes.
