Overcoming Industrial Challenges with High-Purity Oxalic Acid 99.6% (CAS 144-62-7)
For over a decade in chemical manufacturing, we’ve witnessed how inconsistent oxalic acid purity disrupts leather treatment processes—causing uneven dye absorption and product rejects. Researchers repeatedly report batch-to-batch variations undermining experimental reproducibility, while supply chain delays have cost manufacturers millions in production downtime.
A Stable and Reliable Chemical Supply Solution
Our Industrial Grade Oxalic Acid 99.6% addresses these critical pain points through precision manufacturing and strict quality control. With a monthly production capacity of 5000 tons and ISO9001 certification, we ensure consistent supply for both large-scale leather processing plants and specialized research laboratories across 50+ countries.
Typical Industrial Applications
As a dicarboxylic acid with strong reducing properties, Industrial Oxalic Acid 99.6% serves as a key intermediate in leather treatment—effectively removing lime and calcium salts during beamhouse operations. Its chelating ability makes it ideal for water purification systems, where it sequesters metal ions to prevent scale formation. Additional industrial uses include mineral processing, stone cleaning, and as a reducing agent in chemical synthesis.
Why Key Specifications Matter
The 99.6% purity level minimizes impurities that cause side reactions in leather tanning, ensuring uniform collagen fiber modification and predictable dye uptake. Its defined melting point (101-102ºC) guarantees consistent performance in temperature-sensitive processes. The medium strong acidity strikes a critical balance—powerful enough for effective cleaning yet controlled to prevent material degradation. With solubility characteristics strictly verified (soluble in water/ethanol, insoluble in benzene), our product integrates seamlessly into existing industrial workflows without unexpected phase separation issues.
What You Gain With Our Product
Choosing our Ethanedioic Acid 99.6% translates to measurable operational benefits: reduced production waste from consistent quality, lower rework costs due to reliable performance, and compliance with international trade standards through complete documentation. Unlike low-purity alternatives that risk equipment corrosion and product contamination, our SGS-tested oxalic acid delivers predictable results that protect your manufacturing reputation and bottom line.
Why You Can Trust Us
Our quality assurance protocol includes triple-stage HPLC testing for purity verification, with each batch accompanied by a detailed Certificate of Analysis. We maintain full traceability from raw material sourcing to final packaging, and offer unconditional products replacement if specifications are not met. Our manufacturing facility operates under ISO9001 standards, with production processes audited annually by third-party inspectors. As a veteran chemical exporter with 10+ years of experience serving 10000+ industrial clients, we provide responsive technical support to address application-specific challenges.
Certificate of Analysis & Documentation
Every shipment includes a batch-specific COA with detailed purity testing results and compliance data. MSDS documents are provided in multiple languages to meet regional safety requirements. For critical applications, customers may request access to raw HPLC chromatograms and impurity profile reports by referencing their 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.
