Overcoming Industrial Cleaning Challenges with Oxalic Acid 99.6% (CAS 144-62-7)
For over a decade in chemical supply, we've witnessed how inconsistent oxalic acid purity disrupts leather processing lines and stone cleaning operations—impurities causing uneven dye absorption or leaving residue that damages stone surfaces. Clients often struggle with unreliable suppliers who fail to maintain 99.6% minimum purity, leading to production delays and increased quality control costs.
Stable Supply of Industrial Grade Oxalic Acid for Critical Applications
Our Oxalic Acid 99.6% (CAS 144-62-7) addresses these challenges through strict manufacturing controls and a monthly production capacity of 5000 tons, ensuring consistent availability for industrial-scale operations. As a trusted partner to chemical importers and manufacturing enterprises across 50+ countries, we deliver a product that meets the rigorous standards required for leather processing and stone cleaning applications.
Key Industrial Applications
This industrial grade oxalic acid powder serves as a vital component in leather processing, where its reducing properties aid in deliming and bleaching operations, ensuring uniform material preparation. In stone cleaning, its ability to dissolve mineral deposits makes it effective for removing rust stains and efflorescence from natural stone surfaces. Additionally, it finds use as a reducing agent in mining processes, demonstrating versatility across multiple industrial sectors.
The Importance of Purity and Physical Properties
The 99.6% minimum purity of our oxalic acid minimizes副反应 in leather processing, where even small impurities can compromise dye adhesion and product quality. Its white powder form ensures easy handling and precise dosing, while the medium strong acidity (pKa1=1.27, pKa2=4.27) provides optimal reactivity for stone cleaning without excessive surface etching. The well-defined melting point (101-102ºC) and boiling point (365.10 ºC) allow for consistent thermal processing in industrial applications, ensuring batch-to-batch reproducibility that manufacturers rely on.
Quality Assurance for Long-Term Production Efficiency
Choosing our Industrial Grade Oxalic Acid means investing in production stability—reducing rejected batches caused by substandard raw materials and minimizing downtime from supply interruptions. Our ISO9001-certified manufacturing process ensures each 25kg bag meets the same high standards, while compliance with international shipping regulations (UN No. 3261) simplifies cross-border logistics. Unlike low-purity alternatives that require additional purification steps, our ready-to-use product reduces overall production costs and streamlines your workflow.
Rigorous Quality Control You Can Verify
Every batch undergoes comprehensive testing using HPLC and titration methods to confirm purity, with results documented in a Certificate of Analysis (COA) provided with each shipment. Our quality control laboratory maintains calibration records for all testing equipment, available for audit upon request. We offer a full refund or replacement for any product failing to meet specified parameters, and our technical support team provides guidance on proper handling and application optimization based on 10+ years of industry experience.
Certificate of Analysis & Documentation
Each delivery includes a batch-specific COA detailing purity, moisture content, and impurity levels, along with an MSDS containing safety handling instructions. For critical applications requiring additional verification, we can provide raw HPLC chromatograms and method validation documents upon request, ensuring full transparency in our quality control processes.
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
Begin by submitting an inquiry with your required quantity and delivery port (Qingdao, Tianjin, or Shanghai), and we'll provide a quotation within 24 hours. For first-time buyers, we offer sample quantities for quality evaluation before full order placement. Once specifications are confirmed, we arrange production and inspection, with typical lead times of 7-10 days for standard orders. All shipments include complete customs documentation to facilitate smooth import clearance.
