Industrial Grade Oxalic Acid CAS 144-62-7: Solving Consistency Issues in Leather Processing and Stone Cleaning
We’ve witnessed countless production delays caused by inconsistent oxalic acid purity – 98% one batch, 99% the next – leading to unpredictable dye absorption in leather tanning and uneven stone cleaning results. When impurities exceed 0.5%, etching rates drop by 15%, forcing rework and material waste. Reliable supply chains are equally critical; a 2-week shipment delay once cost a client $40,000 in missed production deadlines.
A Stable and Reliable Chemical Supply Solution
Our Industrial Grade Oxalic Acid CAS 144-62-7 delivers consistent 99.6% purity, eliminating batch-to-batch variations that disrupt production. Backed by 10+ years of chemical export experience and ISO9001 certification, we ensure 5000 tons monthly production capacity to meet even large-scale industrial demands. With loading ports in Qingdao, Tianjin, and Shanghai, we optimize logistics routes to minimize delivery times for clients across 50+ countries.
Typical Industrial Applications
This dicarboxylic acid plays a vital role in multiple industrial processes. In leather manufacturing, it effectively removes lime and calcium salts from hides during deliming, preparing surfaces for uniform tanning. As a cleaning agent, its chelating properties dissolve mineral deposits and rust stains from natural stones without damaging substrates. It also serves as a reducing agent in metal processing and ore flotation, demonstrating versatility across manufacturing sectors.
Why Key Specifications Matter
The 99.6% purity level ensures minimal heavy metal impurities (<0.001%), preventing discoloration in leather products and avoiding surface pitting in stone cleaning applications. Its defined melting point (101-102ºC) guarantees consistent dissolution rates in process water, maintaining stable reaction temperatures critical for uniform deliming. The medium strong acidity (pKa1=1.27) provides controlled etching power, balancing effective cleaning with material protection. Each batch undergoes HPLC analysis to verify these specifications, ensuring process reliability.
What You Gain With Our Product
Using our high-purity oxalic acid reduces production rejects by up to 20% compared to lower-grade alternatives, directly improving profit margins. The strict quality control complies with EU REACH regulations, facilitating export to European markets currently facing chemical supply gaps. Our stable monthly capacity eliminates sudden price fluctuations caused by supply shortages, allowing accurate production cost forecasting. Each 25kg bag is sealed with moisture barrier packaging to maintain shelf stability, reducing material waste from clumping or degradation.
Why You Can Trust Us
Every batch undergoes triple testing: initial in-house analysis via GC-MS, third-party verification by SGS, and final inspection before shipment. We provide a detailed COA with each delivery, including specific gravity (1.772 g/cm³), solubility data, and impurity profiles. Our production facility maintains ISO9001 certification, with documented quality control procedures from raw material intake to final packaging. If specifications fail to meet our stated 99.6% purity, we offer full product replacement within 7 days. Technical support engineers are available 24/7 to assist with application-specific questions.
Certificate of Analysis & Documentation
Each shipment includes a batch-specific Certificate of Analysis detailing purity, moisture content, and heavy metal concentrations. MSDS documents with handling precautions and storage guidelines are provided in multiple languages. For critical applications requiring historical data, batch test records can be retrieved using your order reference number for up to 5 years after purchase. Detailed HPLC chromatograms are available upon request to verify purity claims.
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.
How to Place Your Order
Initiate your purchase by submitting an inquiry with your required quantity and delivery location. We’ll provide a detailed quotation including FOB/CIF pricing options within 24 hours. For first-time clients, sample testing is available to verify compatibility with your processes. Once specifications are confirmed, we accept letters of credit or T/T deposits, with balance payment upon B/L issuance. All orders include full customs documentation to streamline import procedures.
