99.6% Oxalic Acid CAS 144-62-7: Resolving Industrial Purity and Supply Challenges
We’ve witnessed countless production disruptions in leather dyeing and marble processing facilities—batch-to-batch purity fluctuations causing uneven dye absorption, excessive impurities leading to surface discoloration on polished marble, and delayed shipments derailing production schedules. With over a decade in chemical supply, we understand that inconsistent raw materials don’t just affect product quality; they erode profitability and client trust.
Stable Supply of Industrial Grade Oxalic Acid for Critical Manufacturing Processes
Our 99.6% Oxalic Acid (CAS 144-62-7) addresses these pain points through rigorous quality control and规模化 production capacity of 5,000 tons monthly. As a key chemical export platform with 10+ years of experience serving 6,000+ global industrial customers, we ensure consistent availability even for large-volume orders, eliminating the risk of production halts due to supply shortages.
Key Industrial Applications of Oxalic Acid
This industrial grade oxalic acid serves as a vital raw material in multiple manufacturing sectors. In leather processing, its strong reducing properties facilitate uniform dye penetration and pH adjustment, ensuring vibrant and consistent coloration. For marble polishing, its chelating ability effectively removes mineral deposits and stains without damaging stone surfaces. Additionally, it functions as a reducing agent in mining operations and cleaning agent for industrial equipment, demonstrating versatility across diverse industrial workflows.
Why Purity and Key Specifications Impact Your Production
The 99.6% purity level of our oxalic acid minimizes副反应 by reducing impurities that could interfere with chemical processes—critical for maintaining product consistency in leather dyeing where even minor composition variations alter color outcomes. The medium strong acidity ensures controlled reactivity, preventing over-etching during marble polishing. With a tightly controlled melting point (101-102ºC) and solubility profile, our product integrates seamlessly into automated production lines, ensuring repeatable results batch after batch. Low heavy metal content, verified through SGS testing, also ensures compliance with EU and North American import standards.
The Value of Reliable Oxalic Acid Sourcing
Choosing substandard oxalic acid risks more than product defects—it can lead to equipment corrosion from unregulated impurities, increased waste from failed batches, and potential regulatory penalties. Our ISO9001-certified production process guarantees each shipment meets strict quality benchmarks, translating to lower long-term costs through reduced rejects and rework. As a trusted supplier to manufacturing enterprises in developing countries and multinational procurement departments, we prioritize the stability that industrial operations depend on.
Our Quality Assurance Commitment
Every batch of our Industrial Grade Oxalic Acid undergoes comprehensive testing using HPLC and titration methods to verify purity and composition. We provide a Certificate of Analysis (COA) with each shipment, detailing key parameters like assay value, moisture content, and impurity levels. Our production facility maintains full traceability from raw material intake to final packaging, and we offer unconditional replacement for any product failing to meet specified standards. With dedicated technical support available 24/7, we don’t just supply chemicals—we ensure your production continuity.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA and MSDS, providing detailed safety and handling information. For critical applications requiring additional verification, we can arrange third-party testing through SGS upon request. Historical batch data is retained for 5 years, allowing customers to review consistency across orders by referencing their purchase order 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.
Streamlined Ordering Process for Industrial Buyers
Initiate your order by submitting an inquiry with your required quantity and delivery timeline. We offer flexible trade terms including FOB Qingdao/Shanghai and CIF to major global ports. For first-time customers, we provide 500g sample units for quality evaluation prior to bulk ordering. Once specifications are confirmed, our production team ensures on-time delivery with full customs documentation support to minimize import delays.
