High-Purity Oxalic Acid 99.6% (CAS 144-62-7): Solving Industrial Purity and Supply Challenges
For over a decade in chemical manufacturing, we’ve witnessed how inconsistent oxalic acid purity disrupts leather processing—causing uneven dye absorption and product defects.科研机构也常因批次差异难以复现实验结果，而供货延迟更会导致生产线停工。These challenges aren’t just inconvenient; they directly impact your bottom line.
Your Reliable Source for Technical Grade Oxalic Acid
Our High-Purity Oxalic Acid 99.6% addresses these critical issues with pharmaceutical-level consistency. As a China Oxalic Acid Supplier with 5000 Tons/Month production capacity, we ensure stable supply to manufacturers across 50+ countries, eliminating the risk of production delays. Whether you’re processing leather or cleaning stones, our technical grade oxalic acid delivers the reliability your operations demand.
Industrial Applications & Functions
This dicarboxylic acid powder plays a pivotal role in multiple industrial sectors. In leather processing, it acts as a deliming agent, removing lime from hides to prepare them for tanning. For cleaning stones, its strong chelating properties effectively dissolve mineral deposits and rust stains. Additionally, it serves as a reducing agent in mining operations and various chemical synthesis processes—all within strictly industrial parameters.
Why Key Specifications Ensure Performance
The 99.6% purity level minimizes impurities that cause副反应 in leather processing, ensuring consistent dye uptake and product quality. Its medium strong acidity (pKa1=1.27, pKa2=4.27) provides optimal reactivity for stone cleaning without damaging surfaces. The precise melting point (101-102ºC) and boiling point (365.10 ºC) ensure stability in high-temperature industrial processes. With a density of 1.772 g/cm³, our oxalic acid offers controlled solubility in water and ethanol, allowing accurate dosage in various applications.
The Value of Consistent Quality in Chemical Sourcing
Choosing our Technical Grade Oxalic Acid means investing in long-term operational efficiency. Unlike lower-grade alternatives that may contain heavy metal impurities, our product meets ISO9001 standards, reducing the risk of equipment corrosion and product contamination. The 25kg bag packaging ensures easy handling and precise storage, while our scalable production capacity guarantees consistent pricing even for large-volume orders. For cleaning stones applications, this translates to predictable results and reduced material waste.
Our Commitment to Quality Assurance
Every batch undergoes rigorous testing through HPLC and titration methods, with full documentation available via COA. We maintain traceability from raw material sourcing to final packaging, ensuring compliance with international shipping regulations (UN No. 3261). Our quality control laboratory operates 24/7, and we offer technical support to help optimize your application processes. If a batch fails to meet specifications, we provide immediate replacement—no questions asked.
Certificate of Analysis & Documentation
Each shipment includes a batch-specific COA with purity test results, heavy metal content, and physical properties. MSDS documents are provided in multiple languages, detailing safe handling procedures and regulatory compliance. For critical applications, we can arrange third-party SGS testing at your request, with results delivered within 48 hours of sample submission.
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 purchase by submitting an inquiry with your required quantity and delivery port (Qingdao, Tianjin, or Shanghai). We’ll provide a detailed quotation including trade terms (FOB/CIF) within 24 hours. For new customers, we offer 500g sample packs for quality verification before bulk ordering. Once specifications are confirmed, standard lead time is 7-10 days for production, with full documentation package sent electronically upon shipment.
