Oxalic Acid Dihydrate 99.6% (CAS 144-62-7): Solving Industrial Purity and Supply Challenges
For over a decade in the chemical supply industry, we’ve witnessed how inconsistent Oxalic Acid Dihydrate purity disrupts leather tanning processes—causing uneven dye absorption and material waste. Mining operations face similar frustrations when substandard products lead to inefficient mineral extraction and increased equipment maintenance. Even small purity fluctuations (as little as 0.5%) can derail production timelines and inflate operational costs for industrial manufacturers.
Stable Supply of High-Purity Oxalic Acid Dihydrate for Critical Industrial Processes
Our Industrial Grade Oxalic Acid Dihydrate addresses these challenges with guaranteed 99.6% purity, ensuring batch-to-batch consistency that eliminates production variables. Backed by a monthly production capacity of 5000 tons and strategically located ports in Qingdao, Tianjin, and Shanghai, we’ve maintained uninterrupted supply for clients across 50+ countries, including leather processing plants and mining operations that depend on reliable chemical inputs.
Key Industrial Applications of Oxalic Acid Dihydrate
As a dicarboxylic acid with strong reducing properties, Oxalic Acid Dihydrate serves as a critical agent in leather processing—effectively removing lime and calcium salts during deliming and bating stages. In mining applications, its chelating ability makes it ideal for mineral processing and metal extraction, particularly in separating rare earth elements. Additional industrial uses include cleaning stone surfaces, acting as a reducing agent in chemical synthesis, and facilitating metal surface treatment processes.
Why 99.6% Purity and Key Specifications Matter in Industrial Use
The 99.6% purity level of our Oxalic Acid Dihydrate minimizes impurity-related副反应, ensuring cleaner processes and higher yields in leather tanning and mining operations. Its defined melting point (101-102ºC) guarantees consistent thermal behavior during industrial reactions, while the medium strong acidity provides controlled reactivity—essential for avoiding material damage in delicate applications. The white powder form ensures uniform mixing and dissolution, preventing uneven distribution that could compromise product quality. Strict solubility characteristics (soluble in water/ethanol, insoluble in benzene) enable precise process design and waste management.
Risk Mitigation and Operational Benefits of Quality Oxalic Acid
Using ISO9001-certified Oxalic Acid Dihydrate reduces the risk of production failures caused by impure chemicals—saving manufacturers from costly rework and downtime. Unlike lower-grade alternatives that may contain heavy metal contaminants, our product meets international export standards, eliminating customs clearance delays. Consistent material quality also optimizes inventory management, as predictable performance reduces the need for excessive safety stock. For leather producers, this translates to uniform product quality and reduced reject rates; for mining operations, it means improved extraction efficiency and lower reagent consumption.
Our Quality Assurance Process: From Production to Delivery
Every batch of our Oxalic Acid Dihydrate undergoes rigorous testing, including composition analysis via HPLC and purity verification through titration methods. We provide a Certificate of Analysis (COA) with each shipment, detailing key parameters like assay value, moisture content, and impurity levels. Our manufacturing facility operates under ISO9001 standards, with continuous monitoring of production processes to maintain the 99.6% purity specification. Should any product fail to meet your requirements, our 30-day quality guarantee ensures prompt replacement or refund. Our technical support team is available to assist with application-specific questions, drawing on years of experience in leather and mining chemical applications.
Certificate of Analysis & Documentation
All orders include a batch-specific COA and MSDS, providing comprehensive safety and quality data for regulatory compliance. For critical applications requiring detailed verification, we can arrange for third-party SGS testing at an additional cost. Historical batch records are maintained for five years, allowing traceability and quality trend analysis for long-term production optimization.
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 Order Process for Industrial Buyers
Initiate your order by submitting an inquiry with your required quantity and delivery timeline. We can arrange sample shipments for qualification testing, typically within 3-5 business days. Once specifications are confirmed, our standard lead time for bulk orders is 7-10 days, with flexible shipping options via major ports. All shipments include complete customs documentation to facilitate smooth import clearance, and our logistics team monitors delivery to ensure on-time arrival.
