Overcoming Industrial Production Challenges with Oxalic Acid 99.6% (CAS 144-62-7)
For over a decade in chemical manufacturing, we've witnessed how inconsistent oxalic acid purity can derail production—causing uneven leather tanning results, ineffective stone cleaning, and costly rework. Many clients initially struggled with suppliers offering "99%" purity that fluctuated batch-to-batch, leading to unpredictable process outcomes and missed delivery deadlines.
A Stable and Reliable Oxalic Acid Supply Solution
Our Industrial Grade Oxalic Acid 99.6% addresses these challenges through stringent quality control and规模化 production. With a monthly capacity of 5000 tons, we ensure consistent availability for large-scale industrial operations, from leather processing plants to stone restoration facilities across 50+ countries. The high purity minimizes impurities that could interfere with critical reactions, providing the reliability your production line demands.
Typical Industrial Applications
As a versatile dicarboxylic acid, 99.6% Oxalic Acid Powder serves multiple industrial sectors. In leather processing, it functions as a cleaning and deliming agent, preparing hides for tanning with precise pH control. For stone cleaning, its chelating properties effectively remove mineral deposits and rust stains without damaging delicate surfaces. Additionally, it acts as a reducing agent in mining operations and metal treatment processes, demonstrating exceptional performance across diverse manufacturing environments.
Why Key Specifications Matter
The 99.6% purity level is critical for industrial efficiency—lower grades introduce excess water or contaminants that reduce reaction efficacy and increase waste. Our product's controlled solubility (readily dissolving in water and ethanol) ensures uniform mixing in aqueous processes, while the medium strong acidity provides optimal reactivity without excessive corrosiveness. The white powder form guarantees easy handling and accurate dosing, essential for maintaining consistent process parameters. Each batch meets strict ISO9001 standards, ensuring the molecular weight (90.03) and density (1.772 g/cm³) remain within narrow tolerances for reliable industrial performance.
What You Gain With Our Oxalic Acid
Choosing our Industrial Oxalic Acid 99.6% means avoiding the hidden costs of substandard materials: reduced rejections in leather production, fewer stone cleaning re-treatments, and minimized downtime from supply interruptions. Unlike low-purity alternatives that may contain heavy metals or residual solvents, our product complies with international export standards, supported by SGS certification. The stable supply chain—backed by multiple loading ports (Qingdao, Tianjin, Shanghai)—ensures your production schedule stays on track, delivering long-term cost savings through process efficiency and reduced waste.
Why You Can Trust Us
Our quality assurance process begins with raw material testing and continues through every production stage, culminating in batch analysis via HPLC and titration. Each shipment includes a Certificate of Analysis (COA) with specific purity data, and MSDS documents for safe handling. We maintain full traceability from production to delivery, with batch records accessible for audit. Our 10+ years of serving international industrial clients have refined our quality control protocols, ensuring that if a batch ever fails to meet specifications, we provide a full replacement at no cost—no questions asked.
Certificate of Analysis & Documentation
Every order includes a batch-specific COA detailing purity (≥99.6%), moisture content, and impurity levels, along with an MSDS containing safety handling instructions and regulatory compliance information. For critical applications requiring detailed analytical data, specific test results (including chromatograms) can be provided upon request with your order reference number.
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 location. We'll provide a quotation including FOB/CIF pricing options, then arrange sample delivery for your testing and approval. Once specifications are confirmed, we'll process your order and coordinate shipping from our nearest port (Qingdao, Tianjin, or Shanghai), with full documentation for customs clearance included.
