Addressing Purity and Supply Challenges with Oxalic Acid CAS 144-62-7
Industrial processes like leather tanning and stone cleaning demand consistent chemical quality—yet many manufacturers face costly disruptions from batch-to-batch purity fluctuations, delayed shipments, and uncertified raw materials. Over our 10+ years serving global industrial clients, we’ve seen how substandard oxalic acid can cause uneven cleaning results, equipment corrosion, and production downtime.
A Stable and Reliable Oxalic Acid Supply Solution
Our 99.6% Oxalic Acid Powder solves these challenges with pharmaceutical-grade consistency and industrial-scale reliability. As a leading chemical export platform with self-operated import-export rights, we maintain 5000 tons/month production capacity and long-term partnerships with ISO9001-certified manufacturers, ensuring steady supply even during peak demand periods.
Typical Industrial Applications
Oxalic Acid CAS 144-62-7 is widely utilized as a Leather Cleaning Acid for deliming and dehairing processes, effectively removing lime deposits while preserving leather structure. In stone cleaning operations, Stone Cleaning Oxalic Acid acts as a powerful yet controlled etching agent, removing mineral stains and efflorescence from granite, marble, and concrete surfaces. It also serves as a reducing agent in mining operations and a key intermediate in organic synthesis.
Why Key Specifications Matter for Industrial Use
The 99.6% purity level minimizes impurities that cause unwanted side reactions in leather processing, ensuring uniform material quality. Its defined melting point (101-102ºC) guarantees consistent behavior in thermal processes, while the medium strong acidity provides optimal reactivity without excessive material damage. The low heavy metal content, verified through SGS testing, meets strict export standards for EU and North American markets, avoiding customs clearance delays and compliance issues.
What You Gain With Our 99.6% Oxalic Acid Powder
Choosing high-quality Ethanedioic Acid for Industry translates to measurable operational benefits: reduced production waste from consistent material performance, lower rework costs due to reliable cleaning results, and enhanced supply chain stability with monthly production capacity exceeding 5000 tons. Unlike uncertified suppliers, our compliance with ISO9001 standards ensures every batch meets the same rigorous specifications, eliminating the hidden costs of material variability.
Why You Can Trust Our Oxalic Acid Supply
Our quality assurance process includes triple-stage testing: raw material inspection, in-process monitoring, and final product analysis via HPLC and titration methods. Each shipment includes a batch-specific COA with purity, moisture, and impurity data, while MSDS documents provide comprehensive safety handling information. We offer a 30-day quality guarantee—if specifications don’t match our COA, we arrange replacement or full refund. Our dedicated technical team provides pre-purchase application咨询 and post-delivery support to optimize your production processes.
Certificate of Analysis & Documentation
Every order includes a Certificate of Analysis (COA) with batch-specific test results for purity, pH, and heavy metal content. Material Safety Data Sheets (MSDS) containing handling, storage, and emergency procedures are provided in multiple languages. For critical applications, we can arrange third-party SGS testing at an additional cost, with results available within 5 working days 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.
How to Place Your Order for Oxalic Acid
Initiate your purchase by submitting an inquiry with your required quantity, delivery location, and preferred trade term (FOB/CIF). We provide formal quotations within 24 hours, including product specifications and documentation details. For first-time buyers, we offer 500g sample shipments for quality evaluation before bulk ordering.
