Oxalic Acid CAS 144-62-7: Solving Industrial Purity and Supply Challenges
We've witnessed countless production delays caused by inconsistent oxalic acid purity—from leather tanneries facing uneven dye absorption to stone cleaning operations dealing with residue issues. When a batch deviates even 0.5% from the required specification, it disrupts entire manufacturing workflows and wastes valuable resources. After 10+ years serving industrial clients worldwide, we understand that reliable supply and precise quality control aren't just preferences—they're operational necessities.
A Stable and Reliable Chemical Supply Solution
Our Industrial Grade Oxalic Acid addresses these challenges with consistent 99.6% purity, ensuring minimal batch-to-batch variation that industrial processes demand. As a China Oxalic Acid Supplier 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, providing stable supply even during global logistics fluctuations.
Typical Industrial Applications
This versatile compound serves critical roles in multiple industrial sectors. In leather processing, it acts as a key auxiliary agent for deliming and pickling, ensuring proper collagen fiber opening for uniform tanning. For stone cleaning operations, its strong chelating properties effectively remove mineral deposits and rust stains without damaging substrate integrity. Additionally, it functions as a reducing agent in mining processes and finds applications in various chemical synthesis reactions—all under strictly industrial contexts.
Why Key Specifications Matter
The 99.6% purity level is critical for industrial efficiency: higher purity minimizes side reactions in chemical synthesis, reducing byproduct formation and raw material waste. The controlled solubility profile (soluble in water/ethanol, insoluble in benzene) ensures predictable performance in aqueous processing systems common in leather and cleaning applications. Its defined melting point (101-102ºC) allows for precise temperature control in thermal processes, while the medium strong acidity provides effective reactivity without excessive corrosivity. These specifications collectively ensure process repeatability and final product quality consistency.
What You Gain With Our Product
Choosing our Oxalic Acid means investing in production stability and cost efficiency. ISO9001-certified manufacturing processes guarantee compliance with international industrial standards, reducing the risk of rejected batches and associated financial losses. The alternative—using lower purity material—often leads to increased consumption rates, extended processing times, and inconsistent end-product quality, ultimately raising operational costs. Our consistent supply chain eliminates production halts due to material shortages, protecting your production schedules and customer commitments.
Why You Can Trust Us
Our quality assurance protocol includes comprehensive testing via HPLC and titration methods for each production batch, with full traceability from raw material to final packaging. Every shipment includes a detailed Certificate of Analysis (COA) verifying key parameters like purity, moisture content, and heavy metal levels. We maintain complete MSDS documentation in compliance with GHS standards, and offer technical support for proper handling and application optimization. With over a decade of chemical export experience and SGS-audited facilities, we stand behind our product quality with a full replacement guarantee for non-conforming batches.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA with detailed test results for critical parameters including purity, pH, insolubles, and heavy metal content. MSDS documents are provided in multiple languages, covering safe handling, storage requirements, and emergency procedures. For qualification purposes, historical batch data and extended testing reports can be requested for review prior to placing orders.
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 terms (FOB/CIF available). We can provide a sample for qualification testing prior to full order placement. Once specifications are confirmed, we'll arrange production and deliver documentation for customs clearance. Our sales team is available to assist with logistics coordination through major Chinese ports (Qingdao, Tianjin, Shanghai) to ensure timely delivery to your facility.
