Combat Production Delays with Reliable 99.6% Oxalic Acid Dihydrate (CAS 144-62-7)
We’ve witnessed countless production disruptions over 10+ years in chemical supply—batch inconsistencies causing cleaning agent formulation failures, purity fluctuations leading to excessive stone etching, and delayed shipments halting mining operations. These aren’t just inconveniences; they directly impact your bottom line and client trust.
Stabilize Your Supply Chain with Industrial Grade Oxalic Acid Powder
Our Industrial Grade Oxalic Acid Dihydrate Powder eliminates these headaches through stringent manufacturing controls. As a trusted partner to 6,000+ industrial customers worldwide, we ensure each 25kg bag maintains 99.6% purity, critical for consistent performance in leather processing, stone cleaning, and mining applications. With a monthly production capacity of 5,000 tons, we guarantee steady supply even during peak demand periods.
Proven Industrial Applications
This versatile compound serves as a powerful cleaning agent for stone surfaces, effectively removing mineral deposits without damaging substrates. In leather processing, it acts as a key reducing agent, ensuring uniform dye absorption and leather softness. Mining operations rely on its chelating properties for metal extraction, while chemical manufacturing utilizes its dicarboxylic acid structure as an intermediate in organic synthesis.
Why Key Specifications Ensure Performance
The 99.6% purity minimizes impurities that cause unwanted side reactions in cleaning formulations, while its controlled solubility profile ensures optimal dilution rates for stone cleaning applications. The precise melting point (101-102ºC) guarantees stability in high-temperature industrial processes, and the medium strong acidity balance prevents over-etching of sensitive materials. As a saturated dicarboxylic acid, it offers consistent reactivity compared to unsaturated alternatives, critical for reproducible results in large-scale production.
Risk Reduction Through Quality Assurance
Choosing substandard oxalic acid risks product recall due to impurity contamination, production downtime from batch variations, and increased waste disposal costs. Our ISO9001-certified manufacturing ensures each batch meets strict quality benchmarks, supported by SGS third-party testing. The 3261 UN number certification ensures compliant international shipping, avoiding customs delays that plague non-certified suppliers. With Ethanedioic Acid Dihydrate from our Shandong facility, you invest in process reliability rather than reactive problem-solving.
Our Quality Commitment
Every shipment undergoes comprehensive testing including HPLC purity analysis, moisture content verification, and heavy metal screening—results documented in your batch-specific COA. We provide full MSDS documentation for safe handling, and our technical team offers tailored guidance on optimal application parameters. If specifications fall outside our guaranteed range, we arrange full replacement at no cost. Our 10+ years of export experience ensures seamless logistics through Qingdao, Tianjin, or Shanghai ports, with dedicated customs clearance support.
Certificate of Analysis & Documentation
Each delivery includes a detailed Certificate of Analysis with batch-specific test results for purity, density, and solubility. Safety data is provided via MSDS, including storage recommendations and handling precautions. For critical applications requiring additional verification, we can arrange pre-shipment sample testing and provide raw HPLC/GC spectra upon request.
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.
